The incorporation of the leucine analog, beta-hydroxyleucine, or the isoleucine analog, 4-thiaisoleucine, into the MPOC-46B kappa chain interfered with the processing of the oligosaccharide moiety of newly synthesized light chains. Analog-containing chains were secreted with endo-beta-N-acetylglucosaminidase H-sensitive oligosaccharides instead of

Isopenicillin N synthase (IPNS) catalyses the synthesis of isopenicillin N (IPN), the biosynthetic precursor to penicillin and cephalosporin antibiotics. IPNS is a non-heme iron(II) oxidase that mediates the oxidative cyclisation of the tripeptide δ-L-α-aminoadipoyl-L-cysteinyl-D-valine (ACV) to IPN with a concomitant

Intraerythrocytic malaria parasites can obtain nearly their entire amino acid requirement by degrading host cell hemoglobin. The sole exception is isoleucine, which is not present in adult human hemoglobin and must be obtained exogenously. We evaluated two compounds for their
