Role of vitamin B 6 biosynthetic rate in the study of vitamin B 6 synthesis in Escherichia coli.
Nutritional auxotrophs of Escherichia coli synthesize vitamin B(6) compounds at a rate of 1 x 10(-10) to 2 x 10(-10) moles per hr per mg (dry weight) of cells when they are suspended in minimal medium lacking their required nutrients. A few auxotrophs have been found to stop or reduce vitamin B(6) synthesis during such an experiment. These include thiamineless, citrate synthaseless, and pyridox...
متن کاملHyperhomocysteinemia in chronic alcoholism: correlation with folate, vitamin B-12, and vitamin B-6 status.
Serum homocysteine concentrations have been shown to be a sensitive functional indicator of intracellular folate, vitamin B-12, and vitamin B-6 status. Chronic alcoholism is known to interfere with one-carbon metabolism, for which the above vitamins serve as coenzymes. In the present study, these vitamins were assessed in 32 chronic alcoholics and 31 healthy volunteers by measuring blood vitami...

متن کاملVitamin B-6: Its Role in Health and Disease
Pyridoxal 5'-phosphate (PLP) is the major coenzymatic form of pyridoxine. There are over one hundred known pyridoxal 5'-phosphate-dependent reactions, most of which are involved in the metabolism of various amino acids . Pyridoxamine 5'-phosphate can function in aminotransf erase reactions by the cyclic regeneration of the two active phosphate forms. Pyridoxal 5'-phosphate-dependent reactions s...
متن کاملClinical use of cyclooxygenase inhibitors impairs vitamin B-6 metabolism.
BACKGROUND A low circulating vitamin B-6 concentration, which is an independent risk factor for cardiovascular disease, is commonly seen in human inflammation. OBJECTIVE We investigated whether cyclooxygenase inhibitors alter vitamin B-6 metabolism. DESIGN To investigate whether subjects taking a cyclooxygenase inhibitor had an altered vitamin B-6 profile, we conducted a cross-sectional stu...
