FunctionInvolved in interconversion of fumarate and succinate (anaerobic respiration) [catalytic activity: succinate + acceptor = fumarate + reduced acceptor].
ProductProbable fumarate reductase [iron-sulfur subunit] FrdB (fumarate dehydrogenase) (fumaric hydrogenase)
CommentsRv1553, (MTCY48.12c), len: 247 aa. Probable frdB, fumarate reductase, iron-sulfur subunit, highly similar to others e.g. P00364|FRDB_ECOLI fumarate reductase iron-sulfur protein from Escherichia coli strain K12 (243 aa), FASTA scores: opt: 846, E(): 0, (50.0% identity in 242 aa overlap); P20921|FRDB_PROVU fumarate reductase iron-sulfur protein from Proteus vulgaris (245 aa); G64097 fumarate reductase iron-sulfur protein from Haemophilus influenzae (276 aa); etc. Contains PS00198 4Fe-4S ferredoxins, iron-sulfur binding region signature. Note that fumarate reductase forms part of an enzyme complex containing four subunits: a flavoprotein (Rv1552|frdA), an iron-sulfur (Rv1553|frdB), and two hydrophobic anchor proteins (Rv1554|frdC and Rv1555|frdD).
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 of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar 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 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).
