Functioni

Catalytic activityi

Phosphoenolpyruvate + D-arabinose 5-phosphate + H2O = 3-deoxy-D-manno-octulosonate 8-phosphate + phosphate.

Pathwayi: 3-deoxy-D-manno-octulosonate biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes 3-deoxy-D-manno-octulosonate from D-ribulose 5-phosphate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Arabinose 5-phosphate isomerase KdsD (kdsD)
  2. 2-dehydro-3-deoxyphosphooctonate aldolase (kdsA)
  3. no protein annotated in this organism
This subpathway is part of the pathway 3-deoxy-D-manno-octulosonate biosynthesis, which is itself part of Carbohydrate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 3-deoxy-D-manno-octulosonate from D-ribulose 5-phosphate, the pathway 3-deoxy-D-manno-octulosonate biosynthesis and in Carbohydrate biosynthesis.

Pathwayi: lipopolysaccharide biosynthesis
