Biosens Bioelectron
. 2001 Oct;
16(9-12):1035-41.
PMID: 11679286
Changes in the absorbance spectrum of tetraphenylporphyrin sulfonate (TPPS) are observed that are unique for the proteins lysozyme, luciferase, apomyoglobin, myoglobin, gamma globulin, insulin, RNAase, phosphotransacetylase, papain, ovalbumin, bovine serum...

Beach A, Harmon H
J Biochem Toxicol
. 1992 Jan;
7(3):155-61.
PMID: 1479593
The in vitro toxicity of multiple hydrophobic compounds was the focus of this study. A mitochondrial respiratory assay, sensitive to perturbations caused by hydrophobic chemicals, was utilized to measure the...

Biochem Pharmacol
. 1990 Sep;
40(5):1077-81.
PMID: 2167679
Dibucaine-HCl inhibited mitochondrial cytochrome c oxidase activity in intact mitochondria with 50% inhibition occurring at 1.1 mM dibucaine-HCl. Dibucaine-HCl did not prevent the reduction of cytochrome oxidase by ascorbate plus...

Mech Ageing Dev
. 1990 Aug;
55(2):151-9.
PMID: 2172665
The rates of CO binding to cytochrome oxidase at low temperatures were studied in mitochondria isolated from the hearts of 3- and 30-32-month-old male F344/N rats. A single apparent energy...

FEBS Lett
. 1990 Jul;
267(1):167-70.
PMID: 2163896
The rate of recombination of CO with fully reduced cytochrome oxidase in intact beef heart mitochondria was measured after flash photolysis at temperatures between 180 and 230K. At pH 7.4...

. 1990 Mar;
53(1):35-48.
PMID: 2157927
The kinetic parameters of cytochrome oxidase activity in synaptic and non-synaptic brain mitochondria from 3- and 30-month-old rats were determined at room temperature. The value of Km for cytochrome c...
