General annotation
Gene namenuoA
Rv numberRv3145
FunctionInvolved in aerobic|anaerobic respiration [catalytic activity: NADH + ubiquinone = NAD(+) + ubiquinol].
ProductProbable NADH dehydrogenase I (chain A) NuoA (NADH-ubiquinone oxidoreductase chain A)
CommentsRv3145, (MTCY03A2.13c), len: 128 aa. Probable nuoA, integral membrane NADH dehydrogenase, chain A, similar to others e.g. Q9XAQ4|NUOA from Streptomyces coelicolor (119 aa), FASTA scores: opt: 405, E(): 5.4e-20, (68.75% identity in 128 aa overlap); Q9RU86|DR1506 from Deinococcus radiodurans (160 aa), FASTA scores: opt: 327, E(): 9e-15, (40.3% identity in 124 aa overlap); BAB47039|NDHC from Triticum aestivum (Wheat), FASTA scores: opt: 273, E(): 2.6e-11, (38.1% identity in 126 aa overlap); etc. Also similar to a NADH-plastoquinone oxidoreductases e.g. P26303|NU3C_WHEAT|NDHC from Triticum aestivum (Wheat) (120 aa), FASTA scores: opt: 273, E(): 2.6e-1, (38.1% identity in 126 aa overlap). Belongs to the complex I subunit 3 family.

Functional categoryintermediary metabolism and respiration

ProteomicsIdentified 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).
TranscriptomemRNA identified by microarray analysis: transcription repressed at low pH in vitro conditions, which may mimic an environmental signal encountered by phagocytosed bacteria (see Fisher et al., 2002) and down-regulated after 24h and 96h of starvation (see Betts et al., 2002).
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
