The universal enzymatic cofactor vitamin B6 can be synthesized as pyridoxal 5-phosphate (PLP) by the glutamine amidotransferase Pdx1. We show that Saccharomyces cerevisiae Pdx1 is hexameric by analytical ultracentrifugation and by crystallographic 3D

Pyridoxal 5'-phosphate (PLP) is required as a cofactor by many enzymes. The predominant de novo biosynthetic route is catalyzed by a heteromeric glutamine amidotransferase consisting of the synthase subunit Pdx1 and the glutaminase subunit Pdx2. Prev

Two biosynthetic routes for the synthesis of pyridoxal 5'-phosphate (PLP), the biologically active compound of vitamin B6, have been characterized. The major pathway leads to direct formation of PLP from a pentasaccharide and a trisaccharide and is o

The intergenic region linking conjugative transfer and replication copy control modules of IncF plasmids shows conservation of gene homology and organization. Genes distal to finO are coordinately expressed with the upstream transfer operon encoding

Pyridoxal 5-phosphate (PLP), an active form of vitamin B(6), is one of the most versatile cofactors and is involved in numerous biochemical reactions. The main pathway for de novo PLP biosynthesis leads to direct formation of PLP from a pentose and t
