6-Formylpterin was purified by paper chromatography, and bovine pineal hydroxyindole-O-methyltransferase (S-adenosyl-L-methionine:N-acetylserotonin O-methyl-transferase; EC 2.1.1.4) was purified by flat-bed gel electrofocusing. Fractions of the methy

Total fluorescence intensity of human lens extracts increases with degree of lens opacities. This fluorescence increase is not due to an increase of the phosphorylated pteridine like substance (PLS).

Publisher Summary The actions spectrum of light which is involved in the regulation of pineal Hydroxyindole-O-methyltransferase (HIOMT) of adult rats was found to be very similar to that of the visual pigments. The results with retinal HIOMT of rats,

Publisher Summary This chapter defines the incorporation of glucosamine glycosaminoglycans and the influence of corneal epithelium. Multiple extractions of de-epithelialized, minced, or homogenized bovine corneas with 0.15 M NaCl can remove up to 80%

On sequential extraction of bovine corneas with 0.155 M NaCl and 1 M CaCl2 two macromolecular fractions were obtained in a ratio of 0.7–1.5, both containing glycosa-minoglycans and a hexosamine containing non-glycosaminoglycan subfraction.

A compound, believed to be a pteridine, was found which participates in phosphate metabolism. The amount of this fluorescent substance in the living lens depends upon the effect of light. This leads to the speculation that the lens may use absorbed l
