1. The net reaction of -ketoglutamate transaminase is shown below. Fill in the
2. The formation of amino-cycloproyl carboxylate (ACC) is an important step in
plant metabolism, leading to the formation of ethylene. A PLP-dependent
enzyme –ACC-synthase - performs this reaction with S-adenosyl methionine
(SAM) as the substrate. Propose a mechanism for this reaction. (Plant Physiol.
1989, 1036). 3. Gabaculine is an irreversible inhibitor of g-aminobutyrate transaminase (reaction
