Physical and enzymological interaction of Bacillus subtilis proteins required for de novo pyridoxal 5'-phosphate biosynthesis.

Journal of bacteriology - 1 Feb 2004

Belitsky Boris R

Abstract excerpt

Bacillus subtilis synthesizes pyridoxal 5'-phosphate, the active form of vitamin B(6), by a poorly characterized pathway involving the yaaD and yaaE genes. The pdxS (yaaD) mutant was confirmed to be a strict B(6) auxotroph, but the pdxT (yaaE) mutant turned out to be a conditional auxotroph depending on the availability of ammonium in the growth medium. The PdxS and PdxT proteins copurified during affinity...
