CC -!- FUNCTION: Metal-dependent phosphatase that shows phosphatase activity
CC against several substrates, including fructose-1-phosphate and
CC fructose-6-phosphate (By similarity). Its preference for fructose-1-
CC phosphate, a strong glycating agent that causes DNA damage rather than
CC a canonical yeast metabolite, suggests a damage-control function in
CC hexose phosphate metabolism (By similarity). Has also been shown to
CC have O-methyltransferase activity that methylates glutamate residues of
CC target proteins to form gamma-glutamyl methyl ester residues (By
CC similarity). Possibly methylates PCNA, suggesting it is involved in the
CC DNA damage response (By similarity). {ECO:0000250|UniProtKB:Q04371,
CC ECO:0000250|UniProtKB:Q9H993}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=beta-D-fructose 1-phosphate + H2O = D-fructose + phosphate;

CC Evidence={ECO:0000250|UniProtKB:Q04371};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=beta-D-fructose 6-phosphate = D-glyceraldehyde 3-phosphate +
CC dihydroxyacetone; Xref=Rhea:RHEA:28002, ChEBI:CHEBI:16016,
CC ChEBI:CHEBI:57634, ChEBI:CHEBI:59776;
CC Evidence={ECO:0000250|UniProtKB:Q04371};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-glutamyl-[protein] + S-adenosyl-L-methionine = [protein]-L-
CC glutamate 5-O-methyl ester + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:24452, Rhea:RHEA-COMP:10208, Rhea:RHEA-COMP:10311,

CC Evidence={ECO:0000250|UniProtKB:Q04371};
CC Name=Ni(2+); Xref=ChEBI:CHEBI:49786;
CC Evidence={ECO:0000250|UniProtKB:Q04371};
CC -!- DOMAIN: Subfamily III proteins have a conserved RTxK motif about 40-50
CC residues from the C-terminus; the threonine may be replaced by serine
CC or cysteine. {ECO:0000250|UniProtKB:Q04371}.
CC -!- PTM: Automethylated. {ECO:0000250|UniProtKB:Q9H993}.
CC -!- SIMILARITY: Belongs to the damage-control phosphatase family. Sugar
CC phosphate phosphatase III subfamily. {ECO:0000305}.
CC -!- CAUTION: Human C6orf211 has been reportedly associated with a protein
CC carboxyl methyltransferase activity, but whether this protein indeed
CC has such an activity remains to be determined (By similarity). It has
CC been later shown to belong to a family of metal-dependent phosphatases
CC implicated in metabolite damage-control (By similarity).
