Dihydropteroate synthase (DHPS) is a key enzyme in bacterial folate synthesis and the target of the sulfonamide class of antibacterials. Resistance and toxicities associated with sulfonamides have led to a decrease in their clinical use. Compounds that bind to the

A strategy based on negative ion electrospray ionization tandem mass spectrometry and closed-ring labeling with both 8-aminopyrene-1,3,6-trisulfonate (APTS) and p-aminobenzoic acid ethyl ester (ABEE) was developed for linkage and branch determination of high-mannose oligosaccharides. X-type cross-ring fragment ions obtained from

The fetus is exposed to almost all of the substances found in the maternal circulation whether nutrients or foreign chemicals ("xenobiotics"). The main route of exposure is the placenta. The placenta is metabolically active toward xenobiotics and the nature of

A modular system for detecting protease activity via enzyme-triggered gel formation is described. Protease-specific recognition sequences are utilized to achieve enzyme specificity. Artificial blood clotting is demonstrated by activating endogenous thrombin to trigger gelation in fibrinogen-deficient blood plasma.

Studies in our laboratory have shown that the N-acetylation activity of the human term placenta is a predominantly attributable to the NAT1 form of arylamine N-acetyltransferase (NAT). To further assess the acetylation capacity of the placenta, the N-acetylation of the
