Figure 4.

Amino acid sequences of peptides from 200-kDa protein aligned with Sec7 sequences. Protein sequence databases (nonredundant version) were searched with amino acid sequences of nine peptides from the 200-kDa protein using the blast algorithm (19) available on the Internet from the National Center for Biotechnology Information (http://www.ncbi.nlm.nih.gov). One peptide (pk57) was found to have significant similarity to Sec7. Alignment of sequences of the eight other peptides with Sec7 using gene works identified three with significant identity to Sec7. In parentheses is percentage similarity of sequences. ∗, Identical amino acids; †, conservative differences.
