Description

Pyridoxal phosphate (PLP, pyridoxal 5'-phosphate, P5P) is a coenzyme, the active form of vitamin B6. Pyridoxal 5′-phosphate (PLP) is used as a cofactor for a wide range of enzymes including mitochondrial cysteine desulfurase, cystathionine γ-synthase (CGS), ornithine 4,5-aminomutase (OAM), and d-serine dehydratase. The versatility of PLP arises from its ability to covalently bind the substrate, and then to act as an electrophilic catalyst, thereby stabilizing different types of carbanionic reaction intermediates. PLP acts as a coenzyme in all transamination reactions, in various beta-elimination reactions, in the condensation reaction in heme synthesis.

Male Wistar rat (body weight -200 g) was sacrificed by bleeding from the right femoral artery under diethyl ether anesthesia. A thoracic aorta was removed and washed with RPMI 1640 medium to avoid contamination with blood. It was then turned inside out, and cut into short segments of about 1-1.5 mm. Each aortic segment was placed in the center of a well on a 6-well culture plate and covered with 0.5 ml of gel matrix solution reconstituted as described. The solution was allowed to gel at 37°C for 20 min, and then overlaid with 2 ml of RPMI 1640 medium (Gibco, New York, USA) containing 1% of ITS+ (Becton Dickinson Labware, MA, USA). PLP (Pyridoxal phosphate ) was reconstituted in phosphate buffered saline and added on day 1. Incubation was carried out for 10 days in a fully humidified system of 5% C02 in the air at 37°C. The medium was changed on day 7 of the culture.
