DE   3-oxoisoapionate-4-phosphate transcarboxylase/hydrolase.
CA   3-oxoisoapionate 4-phosphate + H2O = (2R)-3-phosphoglycerate + glycolate
CA   + H(+).
CC   -!- The enzyme, which belongs to the RuBisCO-like-protein (RLP)
CC       superfamily, has been characterized from several bacterial species.
CC   -!- It participates in the degradation of D-apionate.
CC   -!- The reaction is initiated by decarboxylation to generate a stabilized
CC       enediolate intermediate, with the sequestered CO2 carboxylating the
CC       adjacent enediolate carbon atom.
CC   -!- The resulting 3-ketose-1-phosphate intermediate is hydrolyzed, as in
CC       the authentic RuBisCO-catalyzed reaction, to generate glycolate and
CC       3-phospho-D-glycerate.
CC   -!- Stereospecificity of 3-oxoisoapionate 4-phosphate has not been
CC       determined.
