Production of S-sulfocysteine from so-called cystine disulfoxide in the presence of aspartate aminotransferase.
S-Sulfocysteine production occurred when so-called cystine disulfoxide was incubated with aspartate aminotransferase and 2-oxoglutarate. Evidence was provided indicating that the alanine sulfinic acid portion of cystine disulfoxide was transaminated and the resulting sulfinylpyruvic acid portion decomposed non-enzymatically to give S-sulfocysteine and pyruvic acid.
