Abstract
|
|
|
The structure analysis of bonito heart ferrocytochrome c was carried out at 2.3
A resolution by X-ray diffraction, and a Kendrew-type skeletal model was built
up. This molecule has an overall egg shape, 35 A in height, 30 A in width and 23
A in thickness; the 5th ligand of the heme iron atom is the N-epsilon atom of
the His-18 imidazole ring and the 6th is the Met-80 sulfur atom. Distinct
alpha-helix regions are found between the N-terminus and reside 11, between 60
and 69, and between 90 and the C-terminus. The most distinct difference between
the conformation of the present molecule and that of the horse oxidized molecule
is the location of the Phe-82 phenyl ring. In the present reduced molecule, the
phyenyl ring is in closer contact with the iron atom and gives influences on the
character of the iron atom. Inside the molecule, at the lower part of the heme
pocket, there is an extended hydrogen bond network including the propionic acid
residues of the heme group. Both Phe-82 and the hydrogen bond network may play a
key role in the function of this molecule.
