GCW_03250

Uniprot: A0A0F6CL61
Description: small primase
EC number: 3.1.26.8
Annotation score: 2 out of 5
Miscellaneous [CC]:
Protein existence: Inferred from homology
Catalytic activity: CATALYTIC ACTIVITY: Endonucleolytic cleavage of RNA, removing 21 and 42 nucleotides, respectively, from the 5'- and 3'-termini of a 5S-rRNA precursor. {ECO:0000256|HAMAP-Rule:MF_01469}.
Cofactor: COFACTOR: Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP-Rule:MF_01469}; ; Note=Binds two Mg(2+) per subunit. {ECO:0000256|HAMAP-Rule:MF_01469}
Enzyme regulation:
Function [CC]: FUNCTION: Required for correct processing of both the 5' and 3' ends of 5S rRNA precursor. Cleaves both sides of a double-stranded region yielding mature 5S rRNA in one step. {ECO:0000256|HAMAP-Rule:MF_01469}.
