General
dapA catalyzes the formation of dihydrodipicolinate from L-aspartate 4-semialdehyde and pyruvate.
L-aspartate 4-semialdehyde + pyruvate = dihydrodipicolinate + 2H2O.
This protein is eesential for optimal growth of M.tb and found in the cytoplasm as predicted by the WoLFPSORT and Subloc Server. HMMpfam found one domain PF00701 and has Helix Turn Helix secondary structure.
