HIGH RESOLUTION STRUCTURE AND BIOCHEMICAL PROPERTIES OF A RECOMBINANT CATALASE DEPLETED IN IRON

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
