FunctionOxidizes 3-beta-hydroxysterols using NAD+ as cofactor
Product3-beta-hydroxysteroid dehydrogenase
CommentsRv1106c, (MTV017.59c), len: 370 aa. 3-beta-hydroxysteroid dehydrogenase (see Yang et al., 2007). Equivalent to AL049491|MLCB1222_7 Mycobacterium leprae (376 aa) (75.5% identity in 375 aa overlap). Highly similar to Q03704 NAD(P)-dependent cholesterol dehydrogenase from Nocardia sp. (364 aa), FASTA scores: opt: 1789, E(): 0, (74.5% identity in 361 aa overlap). Also similar to U32426|MCU32426_1 3-beta-hydroxy-Delta5-steroid dehydrogenase from Molluscum contagiosum virus (354 aa), FASTA scores: opt: 432, E(): 1.7e-22, (34.6% identity in 347 aa overlap). Also similar to series of Mycobacterium tuberculosis hypothetical proteins described as sugar epimerases or dehydratases e.g. Rv3634c, Rv3784, Rv3464, etc. The transcription of this CDS seems to be activated specifically in host granulomas (see Ramakrishnan et al., 2000).
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified by proteomics at the Statens Serum Institute (Denmark) (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 in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh 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, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
