The Biochemical Journal
|
November 1, 1976
A convenient method of preparation of high-activity urease from Canavalia ensiformis by covalent chromatography and an investigation of its thiol groups with 2,2'-dipyridyl disulphide as a thiol titrant and reactivity probe
R Norris, K Brocklehurst
The Biochemical Journal
|
August 15, 1986
Chemical evidence for the pH-dependent control of ion-pair geometry in cathepsin B. Benzofuroxan as a reactivity probe sensitive to differences in the mutual disposition of the thiolate and imidazolium components of cysteine proteinase catalytic sites
F Willenbrock, K Brocklehurst
The Biochemical Journal
|
September 15, 1984
Natural structural variation in enzymes as a tool in the study of mechanism exemplified by a comparison of the catalytic-site structure and characteristics of cathepsin B and papain. pH-dependent kinetics of the reactions of cathepsin B from bovine spleen and from rat liver with a thiol-specific two-protonic-state probe (2,2'-dipyridyl disulphide) and with a specific synthetic substrate (N-alpha-benzyloxycarbonyl-L-arginyl-L-arginine 2-naphthylamide)
F Willenbrock, K Brocklehurst
The Biochemical Journal
|
August 1, 1983
A re-evaluation of the nomenclature of the cysteine proteinases of Carica papaya and a rational basis for their identification
K Brocklehurst, E Salih
The Biochemical Journal
|
June 1, 1972
Kinetics of the reversible reaction of papain with 5,5'-dithiobis-(2-nitrobenzoate) dianion: evidence for nucleophilic reactivity in the un-ionized thiol group of cysteine-25 and for general acid catalysis by histidine-159 of the reaction of the 5-mercapto-2-nitrobenzoate dianion with the papain-5-mercapto-2-nitrobenzoate mixed disulphide
G Little, K Brocklehurst
The Biochemical Journal
|
September 1, 1983
Investigation of the catalytic site of actinidin by using benzofuroxan as a reactivity probe with selectivity for the thiolate-imidazolium ion-pair systems of cysteine proteinases. Evidence that the reaction of the ion-pair of actinidin (pKI 3.0, pKII 9.6) is modulated by the state of ionization of a group associated with a molecular pKa of 5.5
E Salih, K Brocklehurst
The Biochemical Journal
|
June 1, 1972
Reactivities of the various protonic states in the reactions of papain and of L-cysteine with 2,2'- and with 4,4'- dipyridyl disulphide: evidence for nucleophilic reactivity in the un-ionized thiol group of the cysteine-25 residue of papain occasioned by its interaction with the histidine-159-asparagine-175 hydrogen-bonded system
K Brocklehurst, G Little
The Biochemical Journal
|
December 1, 1977
Benzofuroxan as a thiol-specific reactivity probe. Kinetics of its reactions with papain, ficin, bromelain and low-molecular-weight thiols
M Shipton, K Brocklehurst
The Biochemical Journal
|
April 1, 1976
PH-dependence of the steady-state rate of a two-step enzymic reaction
K Brocklehurst, H B Dixon
The Biochemical Journal
|
February 1, 1979
A necessary modification to the preparation of papain from any high-quality latex of Carica papaya and evidence for the structural integrity of the enzyme produced by traditional methods
