Rv1650, (MTCY06H11.15), len: 831 aa. Probable pheT,Phenylalanyl-tRNA synthetase beta chain, similar to several e.g. SYFB_ECOLI|P07395 from Escherichia coli (795 aa),FASTA scores: opt: 995, E(): 0, (31.8% identity in 847 aa overlap). Belongs to the phenylalanyl-tRNA synthetase beta chain family - subfamily 1.

Probable conserved membrane protein; Functions as a peptidoglycan terminase that cleaves nascent peptidoglycan strands endolytically to terminate their elongation. Belongs to the transglycosylase MltG family.

Probable leucyl-tRNA synthetase LeuS (leucine--tRNA ligase) (LEURS); Rv0041, (MTCY21D4.04), len: 969 aa. Probable leucyl-tRNA synthetase, similar to many. Contains PS00178 Aminoacyl-transfer RNA synthetases class-I signature. Belongs to class-I aminoacyl-tRNA synthetase family.

Rv2552c, (MTCY159.04), len: 269 aa. Probable aroE,shikimate 5-dehydrogenase, equivalent to Q9CCS7|AROE|ML0515 putative shikimate 5-dehydrogenase from Mycobacterium leprae (278 aa), FASTA scores: opt: 1452, E(): 1.8e-77,(81.5% identity in 270 aa overlap). Also highly similar,but longer 101 aa, to Q9KH59|AROE putative shikimate dehydrogenase (fragment) from Mycobacterium marinum (148 aa), FASTA scores: opt: 729, E(): 1.3e-35, (76.35% identity in 148 overlap); Q9F7W3|AROE from Mycobacterium ulcerans (148 aa), FASTA scores: opt: 718, E(): 5.9e-35, (75.7% identity in 148 aa overlap). And al [...]

Probable threonyl-tRNA synthetase ThrS (threonine-tRNA synthetase)(ThrRS) (threonine-tRNA ligase); Catalyzes the attachment of threonine to tRNA(Thr) in a two- step reaction: L-threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). Also edits incorrectly charged L-seryl-tRNA(Thr).

Valine--tRNA ligase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.

Probable signal recognition particle protein Ffh (fifty-four homolog) (SRP protein); Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY (By similarity). Shows GTPase activity; Belongs to the GTP-binding SRP family. SRP54 subfamily.

Isoleucyl-tRNA synthetase IleS; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile) (By similarity).
