Publication Abstract from PubMed
The 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.
