Cloning, expression, crystallization and preliminary X-ray crystallographic analysis of malonyl-CoA-acyl carrier protein transacylase (FabD) from Xanthomonas oryzae pv. oryzae.

ABSTRACT: Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial blight in rice, which is one of the most devastating diseases in rice-cultivating countries. The Xoo0880 (fabD) gene coding for a malonyl-CoA-acyl carrier protein transacylase (MCAT) from Xoo was cloned and expressed in Escherichia coli. MCAT is an essential enzyme that catalyzes a key reaction of fatty-acid synthesis in bacteria and plants: the conversion of malonyl-CoA to malonyl-acyl carrier protein. The FabD enzyme was purified and crystallized in order to elucidate its three-dimensional structure and to determine its enzymatic reaction mechanism and biological importance. The crystal obtained diffracted to 1.9 A resolution and belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 41.4, b = 74.6, c = 9
