| | ndk | Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family. (142 aa) |
| | yfgB | Dual-specificity RNA methyltransferase RlmN; Specifically methylates position 2 of adenine 2503 in 23S rRNA and position 2 of adenine 37 in tRNAs. m2A2503 modification seems to play a crucial role in the proofreading step occurring at the peptidyl transferase center and thus would serve to optimize ribosomal fidelity; Belongs to the radical SAM superfamily. RlmN family. (382 aa) |
| | yfgA | YfgA protein; Unknown function. (158 aa) |
| | hisS | Histidine--tRNA ligase; Protein synthesis. (432 aa) |
| | b2511 | GTPase Der; GTPase that plays an essential role in the late steps of ribosome biogenesis; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. EngA (Der) GTPase family. (456 aa) |
| | pckA | Phosphoenolpyruvate carboxykinase (ATP); Involved in the gluconeogenesis. Catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) through direct phosphoryl transfer between the nucleoside triphosphate and OAA. Belongs to the phosphoenolpyruvate carboxykinase (ATP) family. (541 aa) |
| | aroK | Shikimate kinase; Catalyzes the specific phosphorylation of the 3-hydroxyl group of shikimic acid using ATP as a cosubstrate; Belongs to the shikimate kinase family. (186 aa) |
| | trpS | Tryptophan--tRNA ligase; Catalyzes the attachment of tryptophan to tRNA(Trp). Belongs to the class-I aminoacyl-tRNA synthetase family. (334 aa) |
| | asnB | AsnB protein; Amino acid biosynthesis. (545 aa) |
| | glnA | Glutamine synthetase; Amino acid biosynthesis. (467 aa) |
| | thrA | Bifunctional aspartokinase/homoserine dehydrogenase; Amino acid biosynthesis; In the C-terminal section; belongs to the homoserine dehydrogenase family. (815 aa) |
| | glyQ | Glycine--tRNA ligase alpha subunit; Protein synthesis. (302 aa) |
| | glyS | Glycine--tRNA ligase beta subunit; Protein synthesis. (694 aa) |
| | mrcB | MrcB protein; Cell envelope. (596 aa) |
| | proS | Proline--tRNA ligase; Catalyzes the attachment of proline to tRNA(Pro) in a two- step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro). As ProRS can inadvertently accommodate and process non-cognate amino acids such as alanine and cysteine, to avoid such errors it has two additional distinct editing activities against alanine. One activity is designated as 'pretransfer' editing and involves the tRNA(Pro)-independent hydrolysis of activated Ala-AMP. The other activity is designated 'posttransfer' editing and involves deacy [...] (561 aa) |
| | mreB | MreB protein; Cell envelope. (347 aa) |
| | accC | Biotin carboxylase; This protein is a component of the acetyl coenzyme A carboxylase complex; first, biotin carboxylase catalyzes the carboxylation of the carrier protein and then the transcarboxylase transfers the carboxyl group to form malonyl-CoA. (445 aa) |
| | guaB | Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family. (487 aa) |
| | guaA | GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP. (522 aa) |
| | nrdE | Ribonucleoside-diphosphate reductase; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. (704 aa) |
| | nrdI | Protein NrdI; Probably involved in ribonucleotide reductase function. (141 aa) |
