Ornithine decarboxylase (ODC) catalyzes ornithine decarboxylation to yield putrescine, a key precursor of polyamines, and tropane alkaloids (TAs). Here, to investigate in depth the role of ODC in poly
NAMPT (15 ng) and NAPRT (20 ng) were incubated with 20 µM [14C]Nam and [14C]NA for 30 min, respectively, in the presence of 1 µM PRPP (low substrate concentration) without or with 1 mM ATP. NAMPT (96
Using a spectrophotometric assay that measures the hyperchromicity that accompanies the unwinding of a DNA duplex, we have identified an ATP-independent step in the unwinding of a herpes simplex virus
DsrAB-type dissimilatory sulfite reductase is a key enzyme of microbial sulfur-dependent energy metabolism. Sulfur oxidizers also contain DsrL, which is essential for sulfur oxidation in Allochromatiu
