C-TERMINAL COILED-COIL DOMAIN FROM BOVINE IF1


Overview

Bovine IF(1) is a basic, 84 amino acid residue protein that inhibits the hydrolytic action of the F(1)F(0) ATP synthase in mitochondria under anaerobic conditions. Its oligomerization state is dependent on pH. At a pH value below 6.5 it forms an active dimer. At higher pH values, two dimers associate to form an inactive tetramer. Here, we present the solution structure of a C-terminal fragment of IF(1) (44-84) containing all five of the histidine residues present in the sequence. Most unusually, the molecule forms an anti-parallel coiled-coil in which three of the five histidine residues occupy key positions at the dimer interface.

About this Structure
