'''PLASTOCYANIN'''<br />


==Overview==
==PLASTOCYANIN==
The crystal structure of plastocyanin from a green alga, Ulva pertusa, has, been determined at 1.6-A resolution. At its copper site, U. pertusa, plastocyanin has a distorted tetrahedral coordination geometry similar to, other plastocyanins. In comparison with structures of plastocyanins, reported formerly, a Cu(II)-Sdelta(Met92) bond distance (2.69 A) is, shorter by about 0.2 A and a Cu(II)-Sgamma(Cys84) distance is longer by, less than 0.1 A in U. pertusa plastocyanin. These subtle but significant, differences are caused by the structural change at a His-Met loop, (His87-Met92) due to an absence of a O(Asp85)-Ogamma(Ser88) hydrogen bond, which is found in Enteromorpha prolifera plastocyanin. In addition, poplar, and Chlamydomonas reinhardtii plastocyanins with a glutamine at residue 88, ... [[http://ispc.weizmann.ac.il/pmbin/getpm?9933621 (full description)]]
