Gene Rv2992c (gltX)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in translation mechanisms [catalytic activity: ATP + L-glutamate + tRNA(GLU) = AMP + diphosphate + L-glutamyl-tRNA(GLU)]. |
| Product | Glutamyl-tRNA synthetase GltS (glutamate--tRNA ligase) (glutamyl-tRNA synthase) (GLURS) |
| Comments | Rv2992c, (MTV012.06c), len: 490 aa. GltS (alternate gene name: gltX), glutamyl-tRNA synthase, equivalent to O33120|SYE_MYCLE glutamyl-tRNA synthetase from Mycobacterium leprae (502 aa), FASTA scores: opt: 2660, E(): 2.3e-163, (81.35% identity in 488 aa overlap). Also highly similar to others e.g. O86528|SYE_STRCO from Streptomyces coelicolor (494 aa), FASTA scores: opt: 1777, E(): 1.4e-106, (57.45% identity in 484 aa overlap); P22250|SYE_BACSU from Bacillus subtilis (483 aa), FASTA scores: opt: 1099, E(): 5.4e-63, (38.45% identity in 489 aa overlap); O51345|SYE_BORBU|GLTX|BB0372 from Borrelia burgdorferi (Lyme disease spirochete) (490 aa), FASTA scores: opt: 1009, E(): 3.3e-57, (34.85% identity in 491 aa overlap); etc. Belongs to class-I aminoacyl-tRNA synthetase family. |
