Abstract
New syringopeptins SP(SC)-1 and -2 were isolated from culture filtrate s of phytopathogenic bacterium strain SCI of Pseudomonas syringae pv. syringae. These syringopeptins were composed of a beta-hydroxy fatty a cid, a long sequence of aliphatic amino acids, and a lactone moiety of eight amino acids. The amino acid sequences were deduced from a compa rison of their tandem mass sepctra with those of known syringopeptins SP-22a and SP-25a. SP(SC)-1 and SP(SC)-2 resembled SP-22a, but differe d from the latter by 3 amino acids.
