Pathwayi: NAD(+) biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes NAD(+) from deamido-NAD(+) (L-Gln route).
Proteins known to be involved in this subpathway in this organism are:
  1. Glutamine-dependent NAD(+) synthetase (nadE), Glutamine-dependent NAD(+) synthetase (NADSYN1), Glutamine-dependent NAD(+) synthetase (nadE)
This subpathway is part of the pathway NAD(+) biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes NAD(+) from deamido-NAD(+) (L-Gln route), the pathway NAD(+) biosynthesis and in Cofactor biosynthesis.
