Nicotinic acid requirement and degradation by Sesbania rhizobium strain ORS571
Sevhtrriia rliizobiuni strain ORS57 1. which grows in the free-living state at the expense of N, or ammonia. requires nicotinic acid as a growth factor and also uses this vitamin as a nitrogen source in culture medium devoid of ammonia. Consequently, under nitrogen-fixing conditions, Sesbania rhizohiw1 requires about 10-times more nicotinic acid than when grown in the presence of ammonia. The p...
متن کاملNicotinic acid adenine dinucleotide phosphate (NAADP) degradation by alkaline phosphatase.
Nicotinic acid adenine dinucleotide phosphate (NAADP) is a ubiquitous second messenger providing a Ca(2+) trigger in a wide range of cell types. However, its metabolism is not well understood. Here, we demonstrate the presence of endogenous NAADP in HeLa cells. CD38, a promiscuous enzyme described to be involved in NAADP metabolism, was not detectable in HeLa cells. In cell-free extracts of HeL...
متن کاملNicotinic acid inhibits glioma invasion by facilitating Snail1 degradation
Malignant glioma is a formidable disease that commonly leads to death, mainly due to the invasion of tumor cells into neighboring tissues. Therefore, inhibition of tumor cell invasion may provide an effective therapy for malignant glioma. Here we report that nicotinic acid (NA), an essential vitamin, inhibits glioma cell invasion in vitro and in vivo. Treatment of the U251 glioma cells with NA ...
متن کاملRuminal Protein Degradation and Estimation of Rumen Microbial Protein Production
Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing AA supply to the duodenum. Ruminal proteolysis...
