Zinc ion binding structure of bovine heart cytochrome C oxidase in the fully reduced state
The structure was published by Muramoto, K., Hirata, K., Shinzawa-Itoh, K., et al., Aoyama, H., Tsukihara, T., and Yoshikawa, S., in 2007 in a paper entitled "A histidine residue acting as a controlling site for dioxygen reduction and proton pumping by cytochrome c oxidase" (abstract).
This crystal structure
was determined using
at a resolution of 2.6 Å and deposited in 2007.
The experimental data on which the structure is based was not deposited.
