CC   -!- FUNCTION: Catalyzes the condensation of ribulose 5-phosphate with
CC       formaldehyde to form 3-hexulose 6-phosphate. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-ribulose 5-phosphate + formaldehyde = D-arabino-hex-3-ulose
CC         6-phosphate; Xref=Rhea:RHEA:25201, ChEBI:CHEBI:16842,
CC         ChEBI:CHEBI:58121, ChEBI:CHEBI:58542; EC=4.1.2.43;
CC   -!- PATHWAY: One-carbon metabolism; formaldehyde assimilation via RuMP
CC       pathway; D-fructose 6-phosphate from D-ribulose 5-phosphate and
CC       formaldehyde: step 1/2.
CC   -!- SIMILARITY: Belongs to the HPS/KGPDC family. HPS subfamily.
CC       {ECO:0000305}.
