Gene Rv1623c (appC)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in the respiratory chain (at the terminal step): aerobic respiration. Cytochrome D terminal oxidase complex is the component of the aerobic respiratory chain that is supposedly predominant when cells are grown at low aeration [catalytic activity: ubiquinol-8 + O(2) = ubiquinone-8 + H(2)O]. |
| Product | Probable integral membrane cytochrome D ubiquinol oxidase (subunit I) CydA (cytochrome BD-I oxidase subunit I) |
| Comments | Rv1623c, (MTCY01B2.15c), len: 485 aa. Probable cydA (previously known as appC, but renamed cydA to conform with Mycobacterium smegmatis nomenclature), cytochrome D ubiquinol oxidase subunit I, integral membrane protein, similar to others e.g. P26459|APPC_ECOLI|CYXA|CBDA|B0978 cytochrome BD-II oxidase subunit I from Escherichia coli strain K12 (514 aa), FASTA scores: opt: 870, E(): 0, (35.9% identity in 485 aa overlap); AL034355|SCD78_12 from Streptomyces coelicolor (501 aa), FASTA scores: opt: 1099, E(): 0, (48.6% identity in 510 aa overlap); etc. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | 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). |
| Transcriptomics | DNA microarrays show lower level of expression in M. tuberculosis H37Rv than in Rv3676 mutant (See Rickman et al., 2005). DNA microarrays show higher level of expression in M. tuberculosis H37Rv during Mg2+ starvation (See Walters et al., 2006). |
| Mutant | Non-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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
