A) Amino acid sequence alignment of SHP and B) Tree showing relationships among selected species (percentage identities for the branches are indicated). A) Symbols are: Rhodobacter sphaeroides strain 2.4.1 (RS), Rb. sphaeroides strain IL106 (IL), Rhodobacter changlensis (CH), Rhodobacter sp. strain SW2 (SW), Rhodovulum adriaticum (RA), Rhodovulum marinum strain RE (RE), Allochromatium vinosum (AV), Rhodospirillum rubrum (RR), Rhodospirillum centenum (RC), Rhodoferax ferrireducens (RF1 & RF2), Campylobacter fetus (CF), Arcobacter butzleri (AB), and Wolinella succinogenes (WS). The signal peptides as well as the amino acids mentioned in the text are in bold. Helices from the three-dimensional structure are underlined and important residues numbered according to Rb. sphaeroides.
