Experimental Records
RECORD: Rec_0062874 VERIFIED: YES
Provenance & Taxonomy
Litoria genimaculata [Animal]
Maculatin
Structure & Mods
linear peptide [Linear]
canonical L-amino-acid peptide [L]
Bio-Activity Profile

PMID9620615 Evidence URLhttps://pubmed.ncbi.nlm.nih.gov/9620615/
RECORD: Rec_0074890 VERIFIED: YES
Provenance & Taxonomy
Synthetic construct based on Litoria genimaculate [Synthetic]
32630
Structure & Mods
linear peptide [Linear]
mixed L/D amino-acid peptide [Mixed]
Amidation
A: 24%; V: 19%. GRAVY: 1.3. Chemical modification: C-terminal NH2; d-Maculatin 1.1: the same sequence made of D-amino acids (except G) showed essentially the same activity as the WT made of L-amino acids (D=L), indicating membrane targeting. Maculatin 1.1 acid: This peptide made without C-terminal amidation lost activity against most of the bacteria with MIC > 100 ug/ml except for L. lactic (MIC 50 ug/ml).
