A detailed and extensive sequence analysis was performed in order to identify and characterize protein sequences in this family of transmembrane electron transport proteins. According to transmembrane helix predictions, all sequences contain 6 transmembrane helices of which 2-6 are located closely in the same regions of the 26 sequences in the alignment. A mammalian ( Homo sapiens) and a plant ( Arabidopsis thaliana) sequence were selected to build 3-dimensional structures at atomic detail using molecular modeling tools. The main structural constraints included the 2 pairs of heme-ligating His residues that are fully conserved in the family and the lipid-facing sides of the helices, which were also very well conserved. The current paper proposes 3-dimensional structures which to our knowledge are the first ones for any protein in the cyt b(561) family. The highly conserved His residues anchoring the two hemes on the cytoplasmic side and noncytoplasmic side of the membrane are in all proteins located in the transmembrane helices 2, 4 and 3, 5, respectively. Several highly conserved amino acids with aromatic side chain are identified between the two heme ligation sites. These residues may constitute a putative transmembrane electron transport pathway. The present study demonstrates that the structural features in the cyt b(561) family are well conserved at both the sequence and the protein level. The central 4-helix core represents a transmembrane electron transfer architecture that is highly conserved in eukaryotic species."xsd:string |
