FIG. 1.

Aligned nucleotide and deduced amino acid sequences used to design forward and reverse group I PCR primers IICRFORB and GRPI571AR, respectively. Dots indicate the same nucleotides or amino acids as in the Alteromanas sp. strain 0-7 sequence. The forward priming site is located in the hydrolytic domain, while the reverse priming site is approximately 900 bp downstream. The nucleotide sequences of the chiA genes of Alteromonas sp. (39), A. caviae (35), S. marcescens (22), and E. agglomerans (19) were obtained from GenBank.
