Abstract
The Foerster resonance energy transfer-based sensor, PENN, measures intracellular phospholipase A(2) (PLA(2)) activity in living cells and small organisms. In an attempt to modify the probe for the detection of particular isoforms, we altered the sn-2 fatty acid in such a way that either one or three of the Z double bonds in arachidonic acid were present in the sensor molecule. Arachidonic-acid-mimicking fatty acids were prepared by copper-mediated coupling reactions. Probes with a single double bond in the 5-position exhibited favorable substrate properties for secretory PLA(2)s. In vitro experiments with the novel unsaturated doubly labeled phosphatidylethanolamine derivatives showed preferred cleavage of the sensor PENN2 (one double bond) by the physiologically important group V sPLA(2), while the O-methyl-derivative PMNN2 was accepted best by the isoform from hog pancreas. For experiments in living cells, we demonstrated that bioactivation via S-acetylthioethyl (SATE) groups is essential for probe performance. Surprisingly, membrane-permeant versions of the new sensors that contained double bonds, PENN2 and PENN3, were only cleaved to a minor extent in HeLa cells while the saturated form, PENN, was well accepted.

Abstract
Different types of enzyme-catalyzed processes are reviewed, with particular regard to those procedures leading to the generation of chiral compounds of high optical purity. The main body of the review deals with hydrolyses and esterification as well as the reduction and oxidation of organic substrates. Other biotransformations of current and/or future importance in the synthesis of homochiral fine chemicals (such as the formation of carbon-carbon bonds using aldolases) are also discussed in some detail. Attention is drawn to current trends in the area and, to this end, a majority of the references are taken from journals published during the period April 1987 to September 1988.
