Use wild characters " ? " and " * " for efficient search:
  • ? : A single character. E.g., trehalose?phosphatase covers both trehalose phosphatase and trehalose-phosphatase, of which, only the latter fits the nomenclature used in this database.
  • * : Any number of characters. E.g.,tre-* brings all genes from trehalase family; coenzyme*A covers coenzyme A, coenzyme-A, and coenzymeA.

Score table (?) Association scores for KOs best matching to the query gene according to each annotation predictor, and for the accepted KO if there is any (rightmost columns).

The predictors are ordered in decreasing weight of contribution to the decision-making process in SACURE.

See above for the final decision on the annotation of this gene.

Predictor Best scoring KOs Best score K01869 ERROR
KEGG (?) Score represents the annotation in KEGG database by June 2014.

Takes a value of either 0 (KO is not associated with the query gene) or 1 (KO is associated with the query gene).
K01869 1 1 ERROR
Cluster (?) Score represents the degree of relatedness of a KO to the query gene based on the clustering in the phylogenetic tree of protein sequences (see below for the tree).

Takes values from 0 to 1.
K01869 0.67 0.67 ERROR
myKEGG (?) Score represents the degree of relatedness of a KO to the query gene based on the Smith-Waterman alignment of protein sequence with most similar sequences from all organisms in the KEGG database.

Takes values from 0 to 1.

KOunknown indicates the score for sequences without any KO association in KEGG database.
K01869 1.00 1.00 ERROR
Tree (?) Score shows the degree of relatedness of a KO to the query gene based on the density of this KO in the phylogenetic tree of protein sequences (see below for the tree).

Takes values from 0 to 2 as the score is normalized to the second best KO.

KOunknown indicates the score for sequences without any KO association in KEGG database.
K01869 1.97 1.97 ERROR
KOG (?) Score indicates the absence or presence of a KO in association with one of the orthologs of the query gene according to a eukaryotic orthology database independent of KEGG (see HELP in the upper menu for details).

Takes a value of either 0 (absent) or 1 (present).
K01869 1 1 ERROR
WormBase (?) Score represents matching between the KEGG descriptions of a KO (KO name and all related enzyme names) and the descriptions of the query gene in WormBase (gene overview and protein domains).

Value is increased by 0.5 for every perfect word match and reduced by 0.1 for each character interruption. A non-matching word always creates a 0 score.

WormBase description used for this gene was:

"Aminoacyl-tRNA synthetase, class I (M) $ Aminoacyl-tRNA synthetase, class I, conserved site $ Aminoacyl-tRNA synthetase, class Ia $ Anticodon-binding $ Leucyl-tRNA synthetase, class Ia, bacterial/mitochondrial $ Rossmann-like alpha/beta/alpha sandwich fold $ tRNA synthetases class I (I, L, M and V) $ tRNA synthetases class I (M) $ Valyl/Leucyl/Isoleucyl-tRNA synthetase, class I, anticodon-binding $$ lars-2 encodes the ortholog of human leucyl amino-acyl tRNA synthetase (LARS); in C. elegans, lars-2 is required for normal mitochondrial structure and function, and acts downstream of daf-2 to control lifespan; lars-2 mutants show swollen, disorganized and sometimes fused mitochondria, and live much longer than wild-type worms; a lars-2 GFP translation fusion gene was ubiquitously expressed, with prominent expression in body-wall muscle and neurons and with subcellular localization in the mitochondria; being a tRNA synthetase that charges mitochondrial tRNAs for translation, lars-2 is predicted to specifically compromise mitochondrial electron transport and ATP synthesis, through it's effects on mitochrondrially encoded genes."

► | Localization scores (click to view)▼ | Localization scores (click to hide)

Score table (?) Localization scores for proteins encoded by the query gene.

Each predictor is used to determine whether the protein is localized to mitochondria or other compartment.

Together with other genes and other predictors, these scores were used in the determination of the subcellular location of reactions associated with the query gene (see below for the reactions).

Predictor Mitochondrial Other
Mitoprot (?) Score represents the predicted probability that the protein is targeted to mitochondria (mitochondrial score) or not (other score) according to Mitoprot (click to reach).

If multiple isofoms of the same protein are available the highest scores are shown for each compartment.
0.68 0.92
MitoMiner (?) Score evaluates the evidence for mitochondrial targeting based on the orthologs in 12 eukaryotic model organisms that are in the MitoMiner database (click to reach).

If clear orthologs for the query gene are available in MitoMiner organisms, the score takes a value between 0 and 1 as a function of the ratio of orthologs that have hits (contributes to the mitochondrial score) or no hits (determines the other score) in the database. Mitochondrial score is also a function of the strength of the evidence for the orthologs found in the database (experimental evidence is given a higher weight than theoretical evidence during scoring).
0.84 0.27
UniProt (?) Score shows the subcellular localization of proteins encoded by this gene as reported in UniProt (click to reach) in October 2014.

If a report is available, the score takes a value of either 0 (not reported to be localized to the pertaining compartment) or 1 (reported to be localized to the pertaining compartment).
Not available Not available
Org. DB (?) Score shows the subcellular localization of proteins encoded by this gene as reported in Organelle Database (click to reach).

If a report is available, the score takes a value of either 0 (not reported to be localized to the pertaining compartment) or 1 (reported to be localized to the pertaining compartment).

Sequence labels indicate KO, taxonomy or model organism, organism name (if taxonomic group), and gene name, respectively. CEL, C. elegans; HSA, H. sapiens; DME, D. melanogaster; ATH, A. thaliana; SCE, S. cerevisiae; BAC, bacteria; ARC, archaea; PRO, protists; FUN, fungi; PLA, plants; INV, invertebrates; NEM, nematodes; ART, arthropods; VER, vertebrates; MAM, mammals. Parenthetical information for organisms other than CEL indicates whether the genes are introduced as best matches (B) or reciprocal best hits (R) to the query gene. Parenthetical information for CEL indicates whether the genes are introduced as paralogues (P) of the query gene or as reciprocal best matches to one of the other organisms in the tree (B). Organism abbreviations are from KEGG.
Reactions
ID Enzyme Reactants Products Genes (?) Multiple genes are separated by OR (I) or AND (&).

I indicates that genes are redundant within the group (e.g. paralogs encoding the same enzyme).
& indicates that genes are non-redundant within the group (e.g. genes encoding different subunits of the same enzyme).

If there are multiple groups of genes, as in an enzyme complex with some enzymes associated with multiple genes, or in a case where the same enzyme is associated with different orthology groups with paralogs, each group with multiple genes is shown in parentheses.
