DXP-independent biosynthesis

The DXP-independent PLP-biosynthetic route consists of a step catalyzed by PLP-synthase, an enzyme composed of two subunits. PdxS catalyzes the condensation of ribulose 5-phosphate, glyceraldehyde-3-phosphate, and ammonia, this latter molecules is produced by PdxT which catalyzes the production of ammonia from glutamine. PdxS is a (β/α)8 barrel (also known as a TIM-barrel) that forms a dodecamer.
