Abstract：
:Broad variation among anoxygenic reaction centers makes it essential to consider a wide variety when considering the origins of photosynthesis. The photosynthetic core antenna domain in the gene pshA from Heliophilum fasciatum was sequenced doubling the number of core sequences available from heliobacteria. The sequence shares a pattern of hydrophobicity and histidine residues with the core antenna domain of pshA from Heliobacillus mobilis. Sequence identity between the two pshA sequences was 68%, indicating heliobacterial reaction centers show similar diversity to photosystem I throughout cyanobacteria and plastids. Thus, the diversity of anoxygenic phototrophic reaction centers may be greater than previously thought.
