Abstract:
YycGF is a crucial signal transduction system for the regulation of cell-wall metabolism in low-G+C Gram-positive bacteria, which include many important human pathogens. The response regulator YycF receives signals from its cognate histidine kinase YycG through a phosphotransfer reaction and elicits responses through regulation of gene expression. The N-terminal regulatory domain of YycF from Bacillus subtilis was overproduced and purified. The protein was crystallized and X-ray data were collected to 1.95 A resolution with a completeness of 97.7% and an overall R(merge) of 7.7%. The crystals belonged to space group P3(1)21, with unit-cell parameters a = b = 59.50, c = 79.06 A.
