Enzyme-mediated peptide synthesis using acylpeptide hydrolase.

European journal of biochemistry

Farries TC, Auffret AD, Aitken A.
PMID: 1688346
Eur J Biochem. 1991 Mar 28;196(3):687-92. doi: 10.1111/j.1432-1033.1991.tb15866.x.

Acylpeptide hydrolase is shown to catalyse the specific addition of a single amino acid to the N-terminus of a peptide. The stabilised Sepharose-coupled form of the enzyme is used to couple a carboxy-methylated N-formyl (or N-acetyl) amino acid to...

Characterisation of freeze-dried wafers and solvent evaporated films as potential drug delivery systems to mucosal surfaces.
