CRYSTAL STRUCTURE OF H129V MUTANT OF ALCALIGENES XYLOSOXIDANS NITRITE REDUCTASE
Overview
Copper nitrite reductases contain both an electron-transfer type 1 Cu site, and a catalytic type 2 Cu site. We have mutated one of the type 2 copper, ligating histidines to observe the effect on catalytic turnover. This, mutation has created a unique site where Cu is ligated by 2 His Nepsilon2, atoms alone.
About this Structure
1WAE is a Single protein structure of sequence from Achromobacter xylosoxidans with CU and ZN as ligands. Active as Transferred entry: 1.7.2.1, with EC number 1.7.99.3 Structure known Active Site: AC1. Full crystallographic information is available from OCA.
