Incorporation of Double-Labeled l-Cystine and dl-Valine in Penicillin
l-[3,3′-(3)H]cystine was incorporated into penicillin with retention of one tritium. This result can be explained by β-lactam formation through ring closure between C3 of cysteine and NH of valine. No radioactivity of dl-[2,3-(3)H]valine was incorporated into penicillin. The loss of isotope at C2 oc...
