Gardimycin, a new antibiotic inhibiting peptidoglycan synthesis. 1977

S Somma, and W Merati, and F Parenti

Gardimycin, a new antibiotic, at 100 mug/ml, specifically inhibited cell wall synthesis and induced accumulation of uridine 5'-diphosphate-N-acetylmur-amylpentapeptide in whole cells of Bacillus subtilis. The antibiotic was active in a particulate enzyme preparation from Bacillus stearothermophilus: 60 mug/ml caused 50%, and 200mug/ml caused 100%, inhibition of peptidoglycan synthesis. Suppression of peptidoglycan synthesis was accompanied by parallel accumulation of the lipid intermediate. This mechanism of action is discussed in comparison with those of other antibiotics that are known to inhibit bacterial cell wall biosynthesis.

UI	MeSH Term	Description	Entries
D009842	Oligopeptides	Peptides composed of between two and twelve amino acids.	Oligopeptide
D010455	Peptides	Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.	Peptide,Polypeptide,Polypeptides
D010457	Peptidoglycan	A structural polymer of the bacterial cell envelope consisting of sugars and amino acids which is responsible for both shape determination and cellular integrity under osmotic stress in virtually all bacteria.	Murein,Pseudomurein
D002473	Cell Wall	The outermost layer of a cell in most PLANTS; BACTERIA; FUNGI; and ALGAE. The cell wall is usually a rigid structure that lies external to the CELL MEMBRANE, and provides a protective barrier against physical or chemical agents.	Cell Walls,Wall, Cell,Walls, Cell
