Function1A1C_MALDO Catalyzes the formation of 1-aminocyclopropane-1-carboxylate, a direct precursor of ethylene in higher plants. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe crystal structure of 1-aminocyclopropane-1-carboxylate (ACC) synthase in complex with the substrate analogue [2-(amino-oxy)ethyl](5'-deoxyadenosin-5'-yl)(methyl)sulfonium (AMA) was determined at 2.01-A resolution. The crystallographic results show that a covalent adduct (oxime) is formed between AMA (an amino-oxy analogue of the natural substrate S-adenosyl-L-methionine (SAM)) and the pyridoxal 5'-phosphate (PLP) cofactor of ACC synthase. The oxime formation is supported by spectroscopic data. The ACC synthase-AMA structure provides reliable and detailed information on the binding mode of the natural substrate of ACC synthase and complements previous structural and functional work on this enzyme.
