Structure and regulation of the gab gene cluster, involved in the gamma-aminobutyric acid shunt, are controlled by a sigma54 factor in Bacillus thuringiensis.

Abstract excerpt

The structure and regulation of the gab gene cluster, involved in gamma-aminobutyric acid (GABA) shunt, were studied by characterizing gabT and gabD genes cloned from Bacillus thuringiensis. Deletions of the gabT and gabD genes in B. thuringiensis strain HD-73 did not affect the growth of mutant strains in rich culture media, but the growth of a gabT deletion mutant strain was reduced in basic media (containing...
