Abstract
We discovered natural photosynthesis using Zn-containing bacteriochlor ophyll a in an acidophilic bacterium Acidiphilium rubrum. Chemical ana lysis of the cell extracts gave a 13:2:1 molar ratio of Zn-bacteriochl orophyll a: Mg-bacteriochlorophyll a: bacteriopheophytin a. Most of th e pigments are associated with fully active reaction center and light- harvesting complexes analogous to those in purple photosynthetic bacte ria. The finding indicates an unexpectedly wide variability of photosy nthesis.
