The amino-acid sequence of the three smallest CNBr peptides from p-hydroxybenzoate hydroxylase from Pseudomonas fluorescens.

Abstract

After CNBr cleavage of p-hydroxybenzoate hydroxylase from Pseudomonas fluorescens, five peptides and free homoserine were isolated (see preceding paper in this journal). The amino acid sequences of the three smallest peptides, viz. CB3, CB4 and CB5, were determined by automated Edman degradation and analysis of enzymatic subdigests. These peptides form a continuous stretch of 110 residues from the N terminus: (Formula: See Text).
