E/Z Diastereoselective Enzymatic Hydrolysis of Esters and Diesters

Abstract

in 1, there are three further interactions <4.7 a (Fe(1)-Fe(1a) = 4.51 A, Fe(2)-Fe(3a) = Fe(2a)-Fe(3) = 4.66 A); the next shortest distance in 3 (Fig. 2 b) is between Fe(3) and Fe(4) at 4.76 A.The magnetic susceptibilities of I and 2 measured against temperature show the same behavior. The effective magnetic moment per iron atom, per,/Fe, of 1 increases from 4.02 pB at room temperature to a maximum value of 4.81 pB at 5 K.( Fig. 3) The variation of x and p are parallel in 1 and 2; the x,, values are about 6 % higher for 1. The coincidence of the data for 1 and 2 seems to rule out monomeric impurities which can cause large increases in x, and p at low temperatures in compounds that interact antiferromagnetically. Therefore the variation observed is a property of the hexameric ion. This is especially important at low temperature, where a sharp increase in p is observed. 600 7 r5.0 [*] Prof.

Cysteine Proteases and Their Inhibitors

“…Here, inhibition by Michael addition is also assumed since the inhibitor reacts with both cysteine 333 and mercaptoethanol 334 under assay conditions. Serine proteases and esterases are not inhibited by this or other similar substances ).…”
