General annotation
Gene namecbs
Rv numberRv1077
FunctionThought to be involved in homocysteine transulfuration [catalytic activity: L-serine + L-homocysteine = cystathionine + H2O]
ProductProbable cystathionine beta-synthase Cbs (serine sulfhydrase) (beta-thionase) (hemoprotein H-450)
CommentsRv1077, (MTV017.30), len: 464 aa. Probable cbs (previously cysM2), cystathionine beta-synthase, similar throughout its length to many eukaryotic cystathionine beta-synthases e.g. P32232|CBS_RAT cystathionine beta-synthase (560 aa), FASTA scores: opt: 951, E(): 0, (40.2% identity in 450 aa overlap); also similar in N-terminal domain (aa 1 - 330) to Rv2334|MTCY98.03 CysK Mycobacterium tuberculosis (310 aa), FASTA scores: opt: 855, E(): 0, (46.8% identity in 314 overlap); and other cysteine synthase proteins e.g. Rv1336, Rv0848, etc. Contains PS00217 Sugar transport proteins signature 2 probably spurious. Belongs to the cysteine synthase/cystathionine beta-synthase family.

ProteomicsThe product of this CDS corresponds to spot 1077 identified in short term culture filtrate by proteomics at the Statens Serum Institute (Denmark), and at the Max Planck Institute for Infection Biology, Berlin, Germany (see citations below). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Detected by 2-DE and MS in M. tuberculosis H37Rv purified from phagosomes of infected murine bone marrow macrophages but not in H37Rv broth-cultures (See Mattow et al., 2006). Identified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011).
Mutationnon essential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website
