Crystal Structure of the Subtilisin Carlsberg:OMTKY3 ComplexCrystal Structure of the Subtilisin Carlsberg:OMTKY3 Complex
Structural highlights
Function[SUBT_BACLI] Subtilisin is an extracellular alkaline serine protease, it catalyzes the hydrolysis of proteins and peptide amides. Evolutionary Conservation![]() Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedOne of the most studied protein proteinase inhibitors is the turkey ovomucoid third domain, OMTKY3. This inhibitor contains a reactive-site loop (Lys13I-Arg21I) that binds in a nearly identical manner to all studied serine proteinases, regardless of their clan or specificity. The crystal structure of OMTKY3 bound to subtilisin Carlsberg (CARL) has been determined. There are two complete copies of the complexes in the crystallographic asymmetric unit. Whereas the two enzyme molecules are virtually identical [0.16 A root-mean-square difference (r.m.s.d.) for 274 C(alpha) atoms], the two inhibitor molecules show dramatic differences between one another (r.m.s.d. = 2.4 A for 50 C(alpha) atoms). When compared with other proteinase-bound OMTKY3 molecules, these inhibitors show even larger differences. This work facilitates a re-evaluation of the importance of certain ovomucoid residues in proteinase binding and explains why additivity and sequence-based binding-prediction methods fail for the CARL-OMTKY3 complex. Structure of the subtilisin Carlsberg-OMTKY3 complex reveals two different ovomucoid conformations.,Maynes JT, Cherney MM, Qasim MA, Laskowski M Jr, James MN Acta Crystallogr D Biol Crystallogr. 2005 May;61(Pt 5):580-8. Epub 2005, Apr 20. PMID:15858268[1] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. See AlsoReferences
