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 [Alcaligenes xylosoxydans xylosoxydans] with CU and ZN as [ligands]. Active as [[1]], with EC number [1.7.99.3]. Full crystallographic information is available from [OCA].
