Analysis of sequence alignments of alkaline phosphatases revealed a correlation between metal specificity and certain amino acid side chains in the active site that are metal-binding ligands. The Zn(2+)-requiring Escherichia coli alkaline phosphatase has an Asp at position 153 and a Lys at position 328. Co(2+)-requiring alkaline phosphatases from Thermotoga maritima and Bacillus subtilis have a...
