Abstract excerpt
CtpA, a carboxyl-terminal processing protease, is a member of a novel family of endoproteases that includes a tail-specific protease from Escherichia coli. In oxygenic photosynthetic organisms, CtpA catalyzes C-terminal processing of the D1 protein of photosystem II, an essential event for the assembly of a manganese cluster and consequent light-mediated water oxidation. We introduced site-specific mutations at...
