title: Thialysine utilization by thialysine resistant CHO cells.
abstract: Thialysine resistant CHO cells utilize thialysine added to the culture medium to a lesser extent than the parental cells. Thialysine is utilized in protein synthesis and it is incorporated into proteins in place of lysine. The parental strain substitutes up to 11% of protein lysine by thialysine, while variant cells substitute a maximum of 5% of protein lysine.
