Identifier

ULAF

Protein name

RecName: Full=L-ribulose-5-phosphate 4-epimerase UlaF; EC=5.1.3.4; AltName: Full=L-ascorbate utilization protein F; AltName: Full=Phosphoribulose isomerase;

Gene name

ulaF

FUNCTION: Catalyzes the isomerization of L-ribulose 5-phosphate to D-xylulose 5-phosphate. Is involved in the anaerobic L-ascorbate utilization (By similarity).

CATALYTIC ACTIVITY: L-ribulose 5-phosphate = D-xylulose 5-phosphate.

COFACTOR: Binds 1 zinc ion per subunit (Potential).

PATHWAY: Cofactor degradation; L-ascorbate degradation; D-xylulose 5-phosphate from L-ascorbate: step 4/4.

INDUCTION: Induced by L-ascorbate. Repressed by UlaR (By similarity).

SIMILARITY: Belongs to the aldolase class II family. AraD/FucA subfamily.

Pfam	PF00596; Aldolase_II; 1;

Isomerase.

Metal-binding, Zinc.
