S. De Rosa et al., A beta-amino acid containing tripeptide from a Pseudomonas - Alteromonas bacterium associated with a Black Sea sponge, J NAT PROD, 63(10), 2000, pp. 1454-1455
A novel tripeptide, 1, was isolated from the extracellular extract of a Pse
udomonas-Alteromonas bacterium that was associated with the Black Sea spong
e Dysidea fragilis. Compound 1 contains the novel beta -aminopimelic acid d
escribed for the first time from a natural product. The structure of 1 is s
uggested on the basis of the analysis of spectroscopic data and chemical de
gradation.
