YkdA and YvtA, HtrA-like serine proteases in Bacillus subtilis, engage in negative autoregulation and reciprocal cross-regulation of ykdA and yvtA gene expression.

Abstract excerpt

HtrA-type serine proteases participate in folding and degradation of aberrant proteins and in processing and maturation of native proteins. Mutation of the corresponding genes often confers a pleiotropic phenotype that can include temperature sensitivity, sensitivity to osmotic and oxidative stress, and attenuated virulence. There are three HtrA-type serine proteases, YkdA, YvtA, and YycK, encoded in the Bacillus...
