Assessment of leukocyte esterase activity in amniotic fluid for the rapid and reliable diagnosis of chorioamnionitis has been demonstrated previously. We compared in vitro inhibition of esterase activity in amniotic fluid with bacterial cultures to identify the origins of the

Homoserine transacetylase (HTA) catalyzes the transfer of an acetyl group from acetyl-CoA to the hydroxyl group of homoserine. This is the first committed step in the biosynthesis of methionine (Met) from aspartic acid in many fungi, Gram-positive and some Gram-negative
Levels of estradiol 17 beta-ester hydrolytic activity in the breast cyst fluid (BCF) from 25 different women with fibrocystic disease of the breast were found to vary over a wide range (0-2.4 nmol/min/mg protein for estradiol acetate). On the basis
[structure: see text] The highly stereocontrolled hydroboration of an alkene, a subsequent Suzuki-Miyaura cross-coupling reaction, a silylcupration on a nonterminal acetylene, and an iododesilylation were the key steps in a convergent total synthesis of (-)-ebelactone A.

The presence of a cysteine residue(s) near the active site of acylpeptide hydrolase was suggested by inactivation of the enzyme with sulfhydryl-modifying agents and by the substantial protection against inactivation afforded by the competitive inhibitor acetylmethionine. 5,5'-dithiobis-(2-nitrobenzoate) titrations of the
