Figure 1.
Fig. 1. . Alignment of the SHP from S. putrefaciens
(PHP), cytochrome c" of M. methylotrophus (16) (MHP), and SHP
from R. sphaeroides (12) (SHP). Heme ligands are colored red,
residues implicated in lining the distal heme pocket are blue,
the sixth heme ligand is green, and the two cysteines linked in
a disulfide bridge are yellow. Residues conserved in all three
sequences have been boxed.
