alpha helical protein
This protein is mostly alpha helical. It
contains 4 amphilphilc helices which are packed other to form a
bundle. The helices are antiparallel in that adjacent helices run in
opposite directions. This motiff is found in several proteins that
are alpha-helical proteins. The helix axes are all aligned with each
other. The sides chains of alpha helices point away from the helix
axis. In this proteins the helices pack together and form a
hydophobic core. The outer faces of the helices are hydrophilic.
This protein contains a heme, and is a reversible electron carrier.
