Gene Rv2109c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Protein degradation |
| Product | Proteasome alpha subunit PrcA; assembles with beta subunit PrcB. |
| Comments | Rv2109c, (MTCY261.05c), len: 248 aa. PrcA, proteasome alpha-type subunit 1. Conserved in M. tuberculosis, M. leprae, M. bovis and M. avium paratuberculosis; predicted to be essential for in vivo survival and pathogenicity (See Ribeiro-Guimaraes and Pessolani, 2007). prcBA genes encode a proteasome with broad substrate specificity (See Lin et al., 2006). |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | The product of this CDS corresponds to spot 2109c identified in short term culture filtrate by proteomics at the Statens Serum Institute (Denmark) (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). Identified in the culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow et al., 2003). Identified in the cell wall fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega 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 the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar et al., 2011). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Proteasome encoded by prcBA genes is essential for persistence and optimal growth in mice; Silencing of prcBA results in increased susceptibility to reactive nitrogen intermediates stress and increased resistance to oxidative stress (See Gandotra et al., 2007).
