A proinsulin-like disulfide insulin precursor is produced from its corresponding linear chain S-sulfonate insulin precursor by reacting the S-sulfonate with a mercaptan in an amount which provides from about 1 to about 5 -SH moieties per -SSO3- moiety in an aqueous medium at a pH of from about 7 to about 11.5 and at an S-sulfonate concentration of up to about 10 mg. per ml. of aqueous medium.
