FIG. 5.

Partial alignments of the A. fundyense amino acid sequences determined in this study. (A) S-Adenosylhomocysteine hydrolase aligned with tobacco (N. sylvestris), yeast (S. pombe), and a cyanobacterium (Synechocystis sp.). (B) Methionine aminopeptidase aligned with yeast (S. cerevisiae), a cyanobacterium (Synechocystis sp.), and E. coli. The shaded areas correspond to three of the five highly conserved copper binding regions that have been described for this enzyme (see text). (C) Histone-like protein aligned with two different histone-like protein sequences from C. cohnii. Boxes denote higher than 50% identity (boldface) or similarity (lightface) among organisms.
