General annotation
FunctionDNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. The beta chain is required for initiation of replication once it is clamped onto DNA, it slides freely (bidirectional and ATP-independent) along duplex DNA [catalytic activity: N deoxynucleoside triphosphate = N diphosphate + {DNA}N].
ProductDNA polymerase III (beta chain) DnaN (DNA nucleotidyltransferase)
CommentsRv0002, (MTV029.02, MTCY10H4.0), len: 402 aa. DnaN, DNA polymerase III (beta chain) (see citations below), equivalent to other Mycobacterial DNA polymerases III beta chain. Also highly similar to others e.g. P27903|DP3B_STRCO DNA polymerase III beta chain from Streptomyces coelicolor (376 aa). Overlaps and extends CDS in neighbouring cosmid MTCY10H4.01.
Functional categoryInformation pathways
ProteomicsIdentified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011).
TranscriptomicsmRNA identified by microarray analysis and up-regulated after 4h of starvation (see Betts et al., 2002).
MutantEssential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
