FIG. 3.

Alignment of the amino acids of three hypothetical domains in Scm, the gene of which is located in the φsc1 genome (domain 1, domain 2, domain 3), with the seven domains in pokeweed mitogen PL-B (PL-B1 to PL-B7). Twelve amino acid residues are conserved in chitin-binding domains and are boldfaced in the PL-B domains. The amino acid residues that are homologous to these conserved amino acids and are present in the three hypothetical domains of Scm are also boldfaced. Several gaps (indicated by dashes) are inserted to obtain maximal homology among these domains.
