ABSTRACT
Effects of methionine-containing dipetides on αs1casein gene expression were investigated in cultured bovine mammary epithelial cells. αs1casein gene expression was higher in the culture added with methionylmethionine than in that with methionine. Addition of methionyllysine enhanced αs1casein gene expression, compared with methionine plus lysine. These results indicated that mammary epithelial cells can utilize methionine-containing dipeptides for milk protein synthesis with a higher efficiency than the respective amino acid.
