===THE CRYSTAL STRUCTURES OF REDUCED PSEUDOAZURIN FROM ALCALIGENES FAECALIS S-6 AT TWO PH VALUES===

~~==Overview==~~

<!--

The ~~structures of~~ the ~~reduced~~ (~~Cu1+) blue-copper protein pseudoazurin from Alcaligenes faecalis strain S-6 are refined~~ at ~~pH 7~~.~~8 and 4~~.4 using X-ray diffraction data to 1.8 A resolution. The final R-factors for the high and low pH structures are 0.178 and 0.177, respectively. Comparing the reduced pseudoazurin at pH 7.8 with the oxidised (Cu2+) ~~molecule~~, ~~small changes are observed in~~ the ~~vicinity of the copper site and on the protein surface~~. ~~At pH 4.4 the copper substituent imidazole of His81 rotates away from the metal with a concurrent movement of the latter towards the plane of the remaining three ligands (S gamma~~-~~Cys78, N delta 1~~-~~His40 and S delta-Met86) thus the geometry of the copper site becomes planar trigonal.~~

The final R-factors for the high and low pH structures are 0.178 and 0.177, respectively. Comparing the reduced pseudoazurin at pH 7.8 with the oxidised (Cu2+) molecule, small changes are observed in the vicinity of the copper site and on the protein surface.
