Inactivation of human S-adenosylhomocysteine hydrolase by covalent labeling of cysteine 195 with thionucleoside derivatives

Thionucleosides 1-4 were synthesized for selectively targeting 195Cys of human placental AdoHcy hydrolase. A new series of 5′-thioadenosine derivatives 1-4 were synthesized for selectively targeting 195Cys of human AdoHcy hydrolase. Their incubation with the enzyme resulted in time- and concentration-dependent inactivation, without major modifications of the NAD+/NADH ratio. The electrospray mass analysis of the inactivated enzyme with 1, 2, 3, and 4b showed that inhibition was accompanied by the formation of a specific and covalent labeling of each AdoHcy hydrolase subunit. Proteolytic cleavage (endo-Lys-C) and subsequent peptide characterization of the labeled enzyme revealed that 195Cys was the residue modified during the inactivation process.
