3.5.99.7 1-amino-2,2-difluorocyclopropane-1-carboxylic acid rac-DFACC, chemical synthesis, overview. Mechanism of decomposition and inhibition of 1-aminocyclopropane-1-carboxylic acid deaminase, and Michaelis-Menten kinetics. DFACC is unstable under near-physiological conditions where it primarily decomposes via specific-base catalysis to 3-fluoro-2-oxobut-3-enoic acid. Different decomposotion mechanisms are described. Upon incubation with ACC deaminase, DFACC is a slow-dissociating inhibitor of ACC deaminase with submicromolar affinity 247567 3.5.99.7 1-amino-2-methylenecyclopopropane-1-carboxylic acid irreversible 114736 3.5.99.7 1-aminocyclopropanephosphonate - 90470 3.5.99.7 5,5'-dithiobis(2-nitrobenzoic acid) - 221 3.5.99.7 aminooxyacetic acid 0.005-1 mM, enzymatic activity is progressively inhibited as the aminooxyacetic acid concentration is increased 1554 3.5.99.7 beta-chloro-Ala - 16065 3.5.99.7 beta-chloro-Ala mechanism-based inhibition 16065 3.5.99.7 beta-fluoro-D-Ala - 96220 3.5.99.7 cyclohexylhydrazine - 96308 3.5.99.7 D-Ala - 291 3.5.99.7 D-Ser slow inactivation 972 3.5.99.7 D-Ser - 972 3.5.99.7 homoserine - 5553 3.5.99.7 KCN - 161 3.5.99.7 L-2-aminobutanoate - 1471 3.5.99.7 L-Ala - 251 3.5.99.7 L-Ser competitive 262 3.5.99.7 L-Ser - 262 3.5.99.7 L-serine 5 mM L-serine results in at least a 50% decrease of measurable ACD activity 95 3.5.99.7 Monoiodoacetamide - 30193 3.5.99.7 NaBH4 - 616 3.5.99.7 NEM - 89 3.5.99.7 NH2CONH-NH2 - 98137 3.5.99.7 NH2OH - 1109 3.5.99.7 O-acetyl-D-Ser - 45778
