FunctionThis protein catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double-stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA [catalytic activity: NAD(+) + (deoxyribonucleotide)(N) + (deoxyribonucleotide)(M) = AMP + nicotinamide nucleotide + (deoxyribonucleotide)(N+M)].
ProductDNA ligase [NAD dependent] LigA (polydeoxyribonucleotide synthase [NAD+])
CommentsRv3014c, (MT3094, MTV012.28c), len: 691 aa. ligA (alternate gene name: lig), DNA ligase NAD-dependent (see citation below), equivalent to O33102|DNLJ_MYCLE|LIGA|LIG|ML1705|MLCB637.10 DNA ligase from Mycobacterium leprae (694 aa), FASTA scores: opt: 3844, E(): 0, (84.7% identity in 687 aa overlap). Also highly similar to many prokaryotic and eukaryotic ligases e.g. Q9Z585|LIGA|SC8D9.06 from Streptomyces coelicolor (735 aa), FASTA scores: opt: 2002, E(): 4e-113, (59.4% identity in 714 aa overlap); P49421|DNLJ_RHOMR|LIGA|LIG from Rhodothermus marinus (712 aa), FASTA scores: opt: 1835, E(): 4.6e-103, (45.55% identity in 685 aa overlap); P15042|DNLJ_ECOLI|LIGA|LIG|DNAL|PDEC|lop|B2411 from Escherichia coli strain K12 (671 aa), FASTA scores: opt: 1696, E(): 1.1e-94, (43.8% identity in 680 aa overlap); etc. Belongs to the NAD-dependent DNA ligase family.
Functional categoryInformation pathways
ProteomicsIdentified in the cytosol, cell wall, and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in whole cell lysates 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).
MutantEssential 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).
