General annotation
| Type | CDS |
| Function | Involved in translation mechanism [catalytic activity: ATP + L-proline + tRNA(pro) = AMP + pyrophosphate + L-prolyl-tRNA(pro)]. |
| Product | Probable prolyl-tRNA synthetase ProS (proline--tRNA ligase) (PRORS) (global RNA synthesis factor) (proline translase) |
| Comments | Rv2845c, (MTCY24A1.12), len: 582 aa. Probable proS, prolyl-tRNA synthetase, highly similar to others e.g. Q9KYR6|SYP_STRCO|pros|SC5H4.23 from Streptomyces coelicolor (567 aa), FASTA scores: opt: 1161, E(): 9e-64, (57.15% identity in 574 aa overlap); P56124|SYP_HELPY|pros|HP0238 from Helicobacter pylori (Campylobacter pylori) (577 aa), FASTA scores: opt: 1082, E(): 6.6e-59, (37.8% identity in 553 aa overlap); P16659|SYP_ECOLI|pros|DRPA|B0194 from Escherichia coli strain K12 (572 aa), FASTA scores: opt: 926, E(): 2.6e-49, (39.85% identity in 587 aa overlap); etc. Contains PS00179 Aminoacyl-transfer RNA synthetases class-II signature 1. Belongs to class-II aminoacyl-tRNA synthetase family. |
