Ionization characteristics of the Cys-25/His-159 interactive system and of the modulatory group of papain: resolution of ambiguity by electronic perturbation of the quasi-2-mercaptopyridine leaving group in a new pyrimidyl disulphide reactivity probe.
Mellor GW, Thomas EW, Topham CM, Brocklehurst K. Mellor GW, et al. Among authors: topham cm. Biochem J. 1993 Feb 15;290 ( Pt 1)(Pt 1):289-96. doi: 10.1042/bj2900289. Biochem J. 1993. PMID: 8439297 Free PMC article.
Structure-function relationships in the cysteine proteinases actinidin, papain and papaya proteinase omega. Three-dimensional structure of papaya proteinase omega deduced by knowledge-based modelling and active-centre characteristics determined by two-hydronic-state reactivity probe kinetics and kinetics of catalysis.
Topham CM, Salih E, Frazao C, Kowlessur D, Overington JP, Thomas M, Brocklehurst SM, Patel M, Thomas EW, Brocklehurst K. Topham CM, et al. Biochem J. 1991 Nov 15;280 ( Pt 1)(Pt 1):79-92. doi: 10.1042/bj2800079. Biochem J. 1991. PMID: 1741760 Free PMC article.
A polyclonal antibody preparation with Michaelian catalytic properties.
Gallacher G, Jackson CS, Searcey M, Badman GT, Goel R, Topham CM, Mellor GW, Brocklehurst K. Gallacher G, et al. Among authors: topham cm. Biochem J. 1991 Nov 1;279 ( Pt 3)(Pt 3):871-81. doi: 10.1042/bj2790871. Biochem J. 1991. PMID: 1953683 Free PMC article.
Structure of chymopapain M the late-eluted chymopapain deduced by comparative modelling techniques and active-centre characteristics determined by pH-dependent kinetics of catalysis and reactions with time-dependent inhibitors: the Cys-25/His-159 ion-pair is insufficient for catalytic competence in both chymopapain M and papain.
Thomas MP, Topham CM, Kowlessur D, Mellor GW, Thomas EW, Whitford D, Brocklehurst K. Thomas MP, et al. Among authors: topham cm. Biochem J. 1994 Jun 15;300 ( Pt 3)(Pt 3):805-20. doi: 10.1042/bj3000805. Biochem J. 1994. PMID: 8010964 Free PMC article.
