N153Q MUTANT OF CYTOCHROME F FROM CHLAMYDOMONAS REINHARDTII
Overview
The structure of cytochrome f includes an internal chain of five water, molecules and six hydrogen-bonding side chains, which are conserved, throughout the phylogenetic range of photosynthetic organisms from higher, plants, algae, and cyanobacteria. The in vivo electron transfer capability, of Chlamydomonas reinhardtii cytochrome f was impaired in site-directed, mutants of the conserved Asn and Gln residues that form hydrogen bonds, with water molecules of the internal chain [Ponamarev, M. V., and Cramer, W. A. (1998) Biochemistry 37, 17199-17208]. The 251-residue extrinsic, functional domain of C. reinhardtii cytochrome f was expressed in, Escherichia coli without the 35 C-terminal residues of the intact, cytochrome that contain the membrane anchor. Crystal structures were, determined ... [(full description)]
