Open reading frames and nucleotide sequence homologies in amplicons for the mutY region amplified from Calyptogena clam symbiont genomes. A, ORFs in the mutY-amplicons. Filled pentagonal column, intact gene. Open pentagonal column, pseudogene or remnant of gene. Gray, part of metA (homoserine O-succinyltransferase). Blue, mutY. B, Aligned mutY-amplicons showing their nucleotide sequence identities and deletion profiles compared with that of the C. phaseoliformis symbiont. Dotted lines, deletions.
