CATALASE COMPOUND II


Overview

Various enzymes use semi-stable ferryl intermediates and free radicals during their catalytic cycle, amongst them haem catalases. Structures for two transient intermediates (compounds I and II) of the NADPH-dependent catalase from Proteus mirabilis (PMC) have been determined by time-resolved X-ray crystallography and single crystal microspectrophotometry. The results show the formation and transformation of the ferryl group in the haem, and the unexpected binding of an anion during this reaction at a site distant from the haem.

About this Structure

2CAG is a Single protein structure of sequence from Proteus mirabilis. The following page contains interesting information on the relation of 2CAG with [Catalase]. Full crystallographic information is available from OCA.
