General annotation (Comments)

Function

Involved in the synthesis of the GDP-mannose and dolichol-phosphate-mannose required for a number of critical mannosyl transfer reactions. Involved in the ascorbic acid (AsA) biosynthesis. Required during the endosperm development. Ref.4 Ref.5

Catalytic activity

D-mannose 6-phosphate = D-fructose 6-phosphate.

Cofactor

Binds 1 zinc ion per subunit By similarity.

Enzyme regulation

Inhibited by EDTA, Zn2+, Cd2+, Co2+, p-chloromercuribenzoate and L-ascorbic acid (AsA). Ref.5

Pathway

Nucleotide-sugar biosynthesis; GDP-alpha-D-mannose biosynthesis; alpha-D-mannose 1-phosphate from D-fructose 6-phosphate: step 1/2.

Tissue specificity

Constitutively expressed in both vegetative and reproductive organs under normal growth conditions (at protein level). Ref.5

Induction

By light (at the protein level). Down-regulated by dark (at the protein level). Down-regulated by DCMU, an exogenous photosynthesis inhibitor. Ref.5

Disruption phenotype

Endosperm development arrested. Ref.4

Sequence similarities

Belongs to the mannose-6-phosphate isomerase type 1 family.

Biophysicochemical properties

Kinetic parameters:

KM=41.3 µM for mannose-6-phosphate Ref.5

Vmax=1.89 µmol/min/mg enzyme with mannose-6-phosphate as substrate

pH dependence:

Optimum pH is 7.5.

Temperature dependence:

Optimum temperature is 52 degrees Celsius.
