Psychrotolerant Paenibacillus tundrae isolates from barley grains produce new cereulide-like depsipeptides (paenilide and homopaenilide) that are highly toxic to mammalian cells.

abstract：:A gene coding for an aminopeptidase (PepC) from Lactococcus lactis subsp. cremoris AM2 was cloned by complementation of an Escherichia coli mutant lacking aminopeptidase activity. The nucleotide sequence was determined. A portion of the predicted amino acid sequence of PepC (436 amino acids) showed strong homology to ...
