Comparison of substrates for measuring cystyl-amino peptidase activity in serum of pregnancy and hepatic disease and in various tissues.

The specificity of substrates for measuring cystyl-amino peptidase activity in pregnant serum in the assessment of placental function was studied, using £-cystine-di-j3-naphthylamide, L-cystine-bis-/?-nitroanilide,/,-cysteine-j3naphthylamide, and S-benzyl-i-cysteine-p-nitroanilide. The enzyme activity with S-benzyl-Z,-cysteine-/?-nitroanilide increased more rapidly and markedly than with other ...

Direct spectrophotometric assay for angiotensin-converting enzyme in serum.

The appropriate conditions for determining angiotensin-converting enzyme in human serum with use of 2-furanacryloyl-L-phenylalanylglycylglycine as substrate are described. The method, a modification of that reported by Holmquist et al. (Anal. Biochem. 95:540-548, 1979) for purified rabbit lung enzyme, is based on the blue shift of the absorption spectrum that occurs upon hydrolysis of the subst...

A spectrophotometric assay for gentamicin.

A rapid and accurate spectrophotometric assay has been developed for the determination of blood werum levels of gentamicin and related antibiotics. The assay uses a purified enzyme from Escherichia coli JR88/C600 that acetylates gentamicin with the production of coenzyme A, linked to a chemical reaction with a sulfhydryl reagent to produce stoichiometric amounts of a sensitive chromophore, moni...

Serum cystyl aminopeptidase activity in the 36th week of pregnancy.

Serum cystyl aminopeptidase (CAS) activity was estimated at 36 weeks' gestation in 209 normotensive pregnancies. The highest activity was found in 31 women who had spontaneous deliveries before 38 weeks' gestation and the lowest in 76 women who were induced after term. The enzyme levels in 117 women who developed hypertension of pregnancy were higher than for normotensives; the highest levels w...

Simplified spectrophotometric assay

A new assay for 3-hydroxy-3-methylglutaryl CoA reductase (mevalonate: NADP oxidoreductase [acylating CoA] , EC 1.1.1.34) is based upon the measurement of released coenzyme A (SH) during the reduction of 3-hydroxy-3-methylglutaryl CoA to mevalonate. Coenzyme A was measured in the presence of dithiothreitol, required for activity, by reaction with 5,5’-dithiobis(2-nitrobenzoic acid). Sodium arsen...
