Abstract

The experiments reported herein constitute part of an investigation of the relationship between primary sequence and higher order structure in repetitive polypeptides. Three series of artificial DNAs encoding poly-peptides represented by the general formula + (GlyAla)_nGlyGlu]_m— were constructed and cloned in Escherichia coli.Protein expression was monitored by in-vivo labeling with ^3H-glycine. Protein products were isolated from the cell lysates by stepwise acidification in yields of 20–50 mg/L of culture, and fusion fragments derived from the cloning vectors were removed by cyanogen bromide cleavage. Amino acid sequence analysis verified the expected sequences through the first 40–50 N-terminal residues.
