An electrophoretic band with butyrylcholinesterase activity was detected in 71 CHE2 C5+ and 378 CHE2 C5- individuals and was named C4/5 in view of its similar mobility to either C4 or C5, depending on the pH of the agar gel used. The present data suggest that C4/5 is a heterologous complex of butyrylcholinesterase. Although the C4/5 band may have the same mobility as C5, depending on the conditions of electrophoresis, our hypothesis is that these two bands result from the association of BChE with different molecules.

Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...

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,...
