The mechanism of 7,8-diaminopelargonate synthase; the role of S-adenosylmethionine as the amino donor.
The product of the first transamination step in the reaction catalysed by diaminopelargonate (DAPA) synthase has been shown to be 4-(S-adenosyl)-2-oxobutanoate, which has been trapped as the corresponding alcohol.
