ProductProbable cold shock-like protein B CspB
CommentsRv0871, (MTV043.64), len: 135 aa. Probable cspB, cold shock-like protein B, equivalent to Z99494|MLCB57_7|MLCB57.11 probable cold shock protein from Mycobacterium leprae (136 aa), FASTA scores: opt: 787, E(): 0, (86.0% identity in 136 aa overlap). Also highly similar (but often longer than) to others e.g. CAB93399.1|AL357524 cold shock protein B from Streptomyces coelicolor (127 aa); Q45099|CSPD_BACCE cold shock-like protein CSPD from Bacillus cereus (66 aa); Y101 81|LLCSPB_1 cold shock protein from Lactococcus lactis (66 aa), FASTA scores: opt: 220, E(): 2.5e-07, (48.3% identity in 60 aa overlap); etc. Seems to belong to the cold-shock domain (CSD) family.
Functional categoryVirulence, detoxification, adaptation
ProteomicsIdentified by proteomics (See Rosenkrands et al., 2000). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
MutantNon-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
