PHOSPHOLIPASE D FROM STREPTOMYCES SP. STRAIN PMF SOAKED WITH THE SUBSTRATE DIBUTYRYLPHOSPHATIDYLCHOLINE.
Overview
Almost all enzyme-catalysed phosphohydrolytic or phosphoryl transfer, reactions proceed through a five-coordinated phosphorus transition state., This is also true for the phospholipase D superfamily of enzymes, where, the active site usually is made up of two identical sequence repeats of an, HKD motif, positioned around an approximate 2-fold axis, where the, histidine and lysine residues are essential for catalysis. An almost, complete reaction pathway has been elucidated by a series of experiments, where crystals of phospholipase D from Streptomyces sp. strain PMF, (PLD(PMF)) were soaked for different times with (i) a soluble poor, short-chained phospholipid substrate and (ii) with a product. The various, crystal structures were determined to a resolution of 1.35-1.75 A for the, ... [(full description)]
