in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Could possibly oxidize fatty acids using specific components [catalytic activity: (3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H(2)O]. |
| Product | Possible enoyl-CoA hydratase EchA21 (enoyl hydrase) (unsaturated acyl-CoA hydratase) (crotonase) |
| Comments | Rv3774, (MTCY13D12.08), len: 274 aa. Possible echA21, enoyl-CoA hydratase, equivalent to Q9CD94|ECHA1|ML0120 putative enoyl-CoA hydratase from Mycobacterium leprae (278 aa), FASTA scores: opt: 1593, E(): 2.2e-92, (88.3% identity in 274 aa overlap). Also similar to others e.g. Q9I2S4|PA1821 from Pseudomonas aeruginosa (270 aa), FASTA scores: opt: 761, E(): 2e-40, (42.3% identity in 267 aa overlap); Q9FHR8 from Arabidopsis thaliana (Mouse-ear cress) (278 aa) FASTA scores: opt: 638, E(): 9.9e-33, (39.4% identity in 269 aa overlap); Q9AB78|CC0353 from Caulobacter crescentus (286 aa), FASTA scores: opt: 601, E(): 2.1e-31, (39.25% identity in 266 aa overlap); etc. |
| Functional category | Lipid metabolism |
