Abstract
The antitumor protein neocarzinostatin is an acidic single-chain molecule, cross-linked by two disulfide bridges, and consists of 109 amino acid residues. Complete disulfide bond reduction and S-carboxymethylation was achieved in liquid ammonia. Sequence determination of five tryptic fragments led to the proposed primary structure.
