CC -!- FUNCTION: Phosphatase which shows a preference for 4'-
CC phosphopantetheine and its oxidatively damaged forms (sulfonate or S-
CC sulfonate), providing strong indirect evidence that the phosphatase
CC activity pre-empts damage in the coenzyme A (CoA) pathway. Hydrolyzing
CC excess 4'-phosphopantetheine could constitute a directed overflow
CC mechanism to prevent its oxidation to the S-sulfonate, sulfonate, or
CC other forms. Hydrolyzing 4'-phosphopantetheine sulfonate or S-sulfonate
CC would forestall their conversion to inactive forms of CoA and acyl
CC carrier protein. May play a role in the physiological regulation of CoA
CC intracellular levels. {ECO:0000250|UniProtKB:Q9NVE7}.

CC -!- ACTIVITY REGULATION: Activity is strongly promoted by Co(2+), Ni(2+),
CC Mg(2+) and Mn(2+). Activity is inhibited by EDTA.
CC {ECO:0000250|UniProtKB:Q9NVE7}.
CC -!- SUBUNIT: Homodimer. Interacts with PKM. {ECO:0000250|UniProtKB:Q923S8}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q923S8}.
CC -!- DOMAIN: Subfamily II proteins have an EGMGR motif about 50 residues
CC from the C-terminus (By similarity). This motif lies near the metal-
CC binding residues in the putative substrate-binding cleft 2 (By
CC similarity). Subfamily II proteins occur only in eukaryotes, in two
CC forms: as a stand-alone unit in plants, and as a C-terminal domain of
CC pantothenate kinases in plants, animals, and chytrid fungi (By
CC similarity). {ECO:0000250|UniProtKB:Q8K4K6}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the type II
CC pantothenate kinase family. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the damage-control
CC phosphatase family. Phosphopantetheine phosphatase II subfamily.
CC {ECO:0000305}.
CC -!- CAUTION: Despite belonging to the type II pantothenate kinase family,
CC the pantothenate kinase domain contains a Val residue at position 147
CC and a Trp residue at position 211 instead of the two conserved active
CC site residues, Glu and Arg. Lacks pantothenate kinase activity.
