CLASS II ALDOLASE HPCH- MAGNESIUM- OXAMATE COMPLEX
Overview
Microorganisms are adept at degrading chemically resistant aromatic, compounds. One of the longest and most well characterized aromatic, catabolic pathways is the 4-hydroxyphenylacetic acid degradation pathway, of Escherichia coli. The final step involves the conversion of, 4-hydroxy-2-oxo-heptane-1,7-dioate into pyruvate and succinic, semialdehyde. This reaction is catalyzed by, 4-hydroxy-2-oxo-heptane-1,7-dioate aldolase (HpcH), a member of the, divalent metal ion dependent class II aldolase enzymes that have great, biosynthetic potential. We have solved the crystal structure of HpcH in, the apo form, and with magnesium and the substrate analogue oxamate bound, to 1.6 A and 2.0 A, respectively. Comparison with similar structures of, the homologous 2-dehydro-3-deoxygalactarate aldolase, ... [(full description)]
