FunctionInvolved at the first step in the common biosynthetic pathway leading from asp to the cell wall precursor MESO-diaminopimelate, to LYS, to met, to ILE and to THR [catalytic activity: ATP + L-aspartate = ADP + 4-phospho-L-aspartate]. Possibly acts in tetramer configuration, tetramer consisting of two alpha (catalytic activity) and two beta (function not known) chains.
ProductAspartokinase Ask (aspartate kinase) [contains: aspartokinase alpha subunit (Ask-alpha); and aspartokinase beta subunit (Ask-beta)]
CommentsRv3709c, (MTV025.057c), len: 421 aa. Ask, aspartokinase (see citation below), equivalent to Q9CB77|ask|ML2323 from Mycobacterium leprae (421 aa), FASTA scores: opt: 2531, E(): 2e-140, (92.65% identity in 421 aa overlap); and P41403|AK_MYCSM|ask from Mycobacterium smegmatis (421 aa), FASTA scores: opt: 2423, E(): 4e-134, (88.1% identity in 421 aa overlap); and to several other organisms e.g. Q9RQ25|ASKA from Amycolatopsis mediterranei (421 aa), FASTA scores: opt: 2026, E(): 5.8e-111, (72.2% identity in 421 aa overlap). Contains PS00324 Aspartokinase signature. Belongs to the aspartokinase family. Alternative products: the alpha and beta subunits of aspartokinase are produced by the use of alternative initiation sites (by similarity). Rv3709c, (MTV025.057c), len: 421 aa. Ask, aspartokinase (see citation below), equivalent to Q9CB77|ask|ML2323 from Mycobacterium leprae (421 aa), FASTA scores: opt: 2531, E(): 2e-140, (92.65% identity in 421 aa overlap); and P41403|AK_MYCSM|ask from Mycobacterium smegmatis (421 aa), FASTA scores: opt: 2423, E(): 4e-134, (88.1% identity in 421 aa overlap); and to several other organisms e.g. Q9RQ25|ASKA from Amycolatopsis mediterranei (421 aa), FASTA scores: opt: 2026, E(): 5.8e-111, (72.2% identity in 421 aa overlap). Contains PS00324 Aspartokinase signature. Belongs to the aspartokinase family. Alternative products: the alpha and beta subunits of aspartokinase are produced by the use of alternative initiation sites (by similarity).
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). 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).
Mutationessential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011).
