Merck, G1424-1MG, Globomycin from Streptomyces hagronensis

General description
Globomycin is a cyclic peptide antibiotic, which inhibits the growth of enteric Gram-negative bacteria through cell wall synthesis inhibition.
Application

Globomycin, a new peptide antibiotic with spheroplast-forming activity. I. Taxonomy of producing organisms and fermentation.: This study explores the taxonomy of the producing organisms of Globomycin and details the fermentation processes involved. This antibiotic shows spheroplast-forming activity, indicating its potential application in targeting bacterial cell wall synthesis (Inukai et al., 1978).

Biochem/physiol Actions
Globomycin was found to inhibit LspA, a lipoprotein signal peptidase. It eliminates the maturation of pro-lipoproteins by inhibition of the enzyme that converts pro-lipoprotein to lipoprotein, acting as a substrate analog of the signal sequence in the outer membrane of Gram-negative bacteria.
