Abstract:
Substrates that are specific for the "hydrolytic" activities of AdoHcy hydrolase have been recently identified. Upon interaction with the AdoHcy hydrolase such substrates generate the "active" electrophiles which then react with the enzyme nucleophiles to produce covalent inhibition. Dihalohomovinyl and haloacetylene analogues derived from adenosine as well 5'-S-allenyl-5'--thioadenosine derivative have been characterized as the first type II mechanism-based inhibitors of AdoHcy hydrolase that rely only on the "hydrolytic" activity. Design and synthesis of the novel adenine nucleosides as well their interaction with AdoHcy hydrolase are discussed in this review.

Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...
Phase I Reactions: Hydrolytic Reactions
An important hydrolytic reaction is ester hydrolysis. Ester bonds, often found in prodrugs, are broken down, increasing the solubility of drugs like aspirin and lidocaine for more straightforward elimination. Amide hydrolysis is another critical reaction, targeting amide bonds prevalent...
