  1. *in addition to the four cbb operons described in this paper, a fifth gene cluster containing cbb genes (including a form II RubisCO gene) has recently been detected in A. ferrooxidans (43). 1Two copies of cbbR and two cbb gene clusters are present on two plasmids; 2two highly similar operons present in the genome; 3in these organisms, trpE gene is neighbor to cbbP but not cbbE. 4 R. eutropha H16 posesses a duplicated cbb operon, with similar copies in the chromosome and in a megaplasmid. 5Data derived from cloned sequences (18). N/D = no data.
