Artificial hemoprotein nanotubes.

A salivary nitrophorin (nitric-oxide-carrying hemoprotein) in the bedbug Cimex lectularius.

Salivary gland homogenate of the bedbug Cimex lectularius caused vasodilation of the preconstricted rabbit aortic ring in the absence of endothelium. Vasodilation was augmented in the presence of superoxide dismutase and inhibited in the presence of Methylene Blue. Utilization of the Griess reaction indicated the presence of reactive nitrogen equivalents of the order of 337 +/- 57 pg equivalent...

Multiplicity of cytochrome P-450 hemoproteins in rat liver microsomes. Preparation and specificity of an antibody to the hemoprotein induced by phenobarbital.

Rat liver microsomes have previously been shown to contain hemoproteins having molecular weights of 53,000, 50,000, and 45,000. The 45,000-dalton hemoprotein, which is induced in rat liver microsomes by pretreatment of animals with phenobarbital, is resistant to proteolysis by trypsin. This characteristic was used to purify it from the other microsomal hemoproteins. In the procedure used, a sod...

Biphasic decrease of radioactive hemoprotein from liver microsomal CO-binding particles. Effect of 3-methylcholanthrene.

The administration of 6-aminolevulinic acid-3, 5-3H to immature male rats leads to the incorporation of radioactivity into the hemoprotein contained in the “CO-binding particles” (steapsin-treated microsomes which do not contain cytochrome bs). A biphasic decrease in the radioactivity incorporated into the hemoprotein in both control and 3-methylcholanthrenetreated rats was observed. Half-life ...
