    The structure of the type I fructose 1,6-bisphosphate aldolase from human muscle has been extended from 3 A to 2 A resolution. The improvement in the resulting electron density map is such that the 20 or so C-terminal residues, known to be associated with activity and isozyme specificity, have been located. The side-chain of the Schiff's base-forming lysine 229 is located towards the centre of an eight-stranded beta-barrel type structure. The C-terminal "tail" extends from the rim of the beta-barrel towards lysine 229, thus forming part of the active site of the enzyme. This structural arrangement appears to explain the difference in activity and specificity of the three tissue-specific human aldolases and helps with our understanding of the type I aldolase reaction mechanism.
