title: The amino acid sequence around the reactive cysteine residue in human plasma Factor XII.
abstract: 1. Activated human plasma factor XIII was 65% inhibited by iodo[(14)C]acetate and incorporated 0.6 mol of label into the alpha subunit, which eventually was allowed to form a precipitate. 2. All the label was recovered as S-carboxymethylcysteine in a tetra-peptide of sequence Gly-Gln-Cys-Trp.
