Murphy A, Coll R
J Biol Chem
. 1993 Nov;
268(31):23307-10.
PMID: 8226854
Incubation of leaky or nonionic detergent-solubilized sarcoplasmic reticulum vesicles in solutions containing magnesium, beryllium, and fluoride caused a time-dependent complete inhibition of calcium ATPase activity. The inhibited state persisted through...

Coll R, Murphy A
J Biol Chem
. 1992 Oct;
267(30):21584-7.
PMID: 1400469
The sarcoplasmic reticulum (SR) CaATPase is inactivated by fluoride in the presence of magnesium (Murphy, A. J., and Coll, R. J. (1992) J. Biol. Chem. 267, 5229-5235). The inactive complex...

Murphy A, Coll R
J Biol Chem
. 1992 Aug;
267(24):16990-4.
PMID: 1387398
The sarcoplasmic reticulum CaATPase forms an inactive complex with fluoride (CaATPase-F), which in the absence of calcium reactivates very slowly (t1/2 approximately 40 h at 25 degrees C). Reactivation is...

Murphy A, Coll R
J Biol Chem
. 1992 Mar;
267(8):5229-35.
PMID: 1531981
Addition of sodium fluoride in the millimolar concentration range to a solution containing the sarcoplasmic reticulum CaATPase undergoing turnover in its vesicular or nonionic detergent-solubilized forms produced a slow (time...

Coll R, Cesar D, HYNES J, Shane B
Biochem Pharmacol
. 1991 Jul;
42(4):833-8.
PMID: 1867639
The in vitro metabolism of a variety of 5,8-dideazafolate and 5,8-dideazaisofolate analogues by pig liver folylpolyglutamate synthetase and the specificity of the enzyme for some polyglutamate derivatives of these analogues...
6.
Coll R, Murphy A
Biochemistry
. 1991 Feb;
30(6):1456-61.
PMID: 1825176
The CaATPase of sarcoplasmic reticulum was reacted with [gamma-32P]ATP to form the covalent phosphoenzyme intermediate. Noncompetitive inhibition by reactive red-120 and chelation of calcium allowed us to monitor single-turnover kinetics...

Coll R, Murphy A
Biochim Biophys Acta
. 1987 Nov;
904(2):227-38.
PMID: 2959323
The triazine dye, Reactive Red 120, was found to bind tightly (Kd = 30) nM) and with low stoichiometry to sarcoplasmic reticulum membranes. Our finding that this high-affinity binding caused...

Coll R, Fink A
Cryobiology
. 1987 Aug;
24(4):332-44.
PMID: 2957172
A comparative study of nucleophilic (methanol), aprotic (dimethyl sulfoxide), and protic but non nucleophilic (ethylene glycol, ethylene glycol/dimethylformamide) solvents on the catalytic and structural properties of human plasmin has been...

Affinity of nucleotides for the active site of detergent-solubilized sarcoplasmic reticulum CaATPase
Coll R, Murphy A
Biochem Biophys Res Commun
. 1986 Jul;
138(2):652-8.
PMID: 2943280
A dye displacement method was developed for determination of the affinities of compounds toward the active site of the detergent-solubilized sarcoplasmic reticulum CaATPase. Titration of the enzyme with 2',3'-O-(2,4,6-trinitrophenyl)-ADP resulted...

J Biol Chem
. 1986 Jan;
261(3):1248-52.
PMID: 3080421
The effect of aqueous methanol cryosolvents on the catalytic and structural properties of bovine trypsin has been investigated. The low freezing points and low viscosities of methanol-based cryosolvents are desirable...
