Reaction pathway of bovine aortic lysyl oxidase.
The catalysis of amine oxidation by lysyl oxidase has been probed to assess for the likely order of substrate binding and product release and to discriminate between mechanistic alternatives previously proposed for other copper-dependent amine oxidases using molecular oxygen as a substrate. Lineweaver-Burk plots revealed a pattern of parallel lines when the oxidation of n-butylamine was followe...
متن کاملIncreased aortic stiffness and attenuated lysyl oxidase activity in obesity.
OBJECTIVE One potential mechanism through which obesity exerts adverse effects on the vascular system is by increasing aortic stiffness, a change known to be predictive of increased cardiovascular mortality. The aim of this study was to investigate the pathophysiology that links obesity to aortic stiffening. APPROACH AND RESULTS Obese (ob/ob) mice were used to examine physical, morphological,...
متن کاملCloning and characterization of a fourth human lysyl oxidase isoenzyme.
We report here the complete cDNA sequence and exon-intron organization of the human lysyl oxidase-like (LOXL)3 gene, a new member of the lysyl oxidase (LO) gene family. The predicted polypeptide is 753 amino acids in length, including a signal peptide of 25 residues. The C-terminal region, residues 529-729, contains a LO domain similar to those in the LOX (the first characterized LO isoenzyme),...
متن کاملPartial characterization of lysyl oxidase from several human tissues.
Lysyl oxidase activity was assayed in urea extracts of a number of human tissues, proving to be highest in skin. Antibodies to human placental lysyl oxidase completely inhibited the activity of crude lysyl oxidase from all the human tissues studied, with no significant differences in the amounts of antiserum required for 50% inhibition. By contrast, marked differences were found in this value b...
متن کاملLysyl oxidase activity and elastin/glycosaminoglycan interactions in growing chick and rat aortas
Hydrophobic tropoelastin molecules aggregate in vitro in physiological conditions and form fibers very similar to natural ones (Bressan, G. M., I. Pasquali Ronchetti, C. Fornieri, F. Mattioli, I. Castellani, and D. Volpin, 1986, J. Ultrastruct. Molec. Struct. Res., 94:209-216). Similar hydrophobic interactions might be operative in in vivo fibrogenesis. Data are presented suggesting that matrix...
