RT "Functional assignment of multiple catabolic pathways for D-apiose.";
RL Nat. Chem. Biol. 14:696-705(2018).
CC -!- FUNCTION: Involved in catabolism of D-apiose. Catalyzes the
CC phosphorylation of L-erythrulose to L-erythrulose 1-phosphate
CC (PubMed:29867142). Can also phosphorylate D-erythrulose and
CC dihydroxyacetone in vitro (PubMed:29867142).
CC {ECO:0000269|PubMed:29867142}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-erythrulose = ADP + H(+) + L-erythrulose 1-phosphate;
CC Xref=Rhea:RHEA:48780, ChEBI:CHEBI:15378, ChEBI:CHEBI:27913,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:58002, ChEBI:CHEBI:456216;
CC EC=2.7.1.209; Evidence={ECO:0000269|PubMed:29867142};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.007 mM for L-erythrulose {ECO:0000269|PubMed:29867142};
CC KM=0.005 mM for D-erythrulose {ECO:0000269|PubMed:29867142};
CC KM=0.015 mM for dihydroxyacetone {ECO:0000269|PubMed:29867142};
CC Note=kcat is 2.76 sec(-1) with L-erythrulose as substrate. kcat is
CC 0.72 sec(-1) with D-erythrulose as substrate. kcat is 1.34 sec(-1)
CC with dihydroxyacetone as substrate. {ECO:0000269|PubMed:29867142};
CC -!- PATHWAY: Carbohydrate metabolism. {ECO:0000269|PubMed:29867142}.
