CC Evidence={ECO:0000256|RuleBase:RU003843};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|RuleBase:RU003843};
CC Note=Binds 2 divalent metal cations per subunit. Magnesium or
CC manganese. {ECO:0000256|RuleBase:RU003843};
CC -!- PATHWAY: Cofactor biosynthesis; riboflavin biosynthesis; 2-hydroxy-3-
CC oxobutyl phosphate from D-ribulose 5-phosphate: step 1/1.
CC {ECO:0000256|ARBA:ARBA00004904, ECO:0000256|RuleBase:RU003843}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|RuleBase:RU003843}.
CC -!- SIMILARITY: Belongs to the DHBP synthase family.
CC {ECO:0000256|RuleBase:RU003843}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
