Bismillahirahmanirrahim. Alhamdulillah, today I want to introduce to all of you about the structure of BOVINE TRYPSIN in 3D and the structure of ISOPENICILLIN N SYNTHASE WITH SUBSTRATE ANALOGUE L,L,D-ACD2AB (UNEXPOSED). Thank you so much to my computer in science lecturer Madam Linda for teaching me this subject for this semester. This topic is quite interesting.I like it so much. We can see the real of any protein structure in 3D that we can observe it clearly on any parts of proteins structure that we like via using RASWIN software.

Isopenicillin N synthase (IPNS) is a non-heme iron(II) oxidase which catalyses the biosynthesis of isopenicillin N (IPN) from the tripeptide delta-l-alpha-aminoadipoyl-l-cysteinyl-d-valine (lll-ACV). Herein we report crystallographic studies to investigate the binding of a truncated lll-substrate in the active site of IPNS. Two epimeric tripeptides have been prepared by solution phase peptide synthesis and crystallised with the enzyme. delta-l-alpha-Aminoadipoyl-l-cysteinyl-d-2-amino-3,3-dideuteriobutyrate (lll-ACd(2)Ab) has the same configuration as the natural substrate lld-ACV at each of its three stereocentres; its epimer delta-l-alpha-aminoadipoyl-l-cysteinyl-l-2-amino-3,3-dideuteriobutyrate (lll-ACd(2)Ab) has the opposite configuration at its third amino acid. lll-ACV has previously been shown to inhibit IPNS turnover of its substrate lld-ACV; the all-protiated tripeptide delta-l-alpha-aminoadipoyl-l-cysteinyl-d-2-aminobutyrate (lld-ACAb) is a substrate for IPNS, being turned over to a mixture of penam and cepham products. Comparisons between the crystal structures of the IPNS:Fe(II):lld-ACd(2)Ab and IPNS:Fe(II):lll-ACd(2)Ab offer a possible rationale for the previously observed inhibitory effects of lll-ACV on IPNS activity.
