DE Type 2 DNA topoisomerase 6 subunit B (EC 5.99.1.3) (Type II DNA DE topoisomerase VI subunit B) (TopoVI-B). GN Name=top6B; OrderedLocusNames=Mbur_1203; OS Methanococcoides burtonii (strain DSM 6242). OC Archaea; Euryarchaeota; Methanomicrobia; Methanosarcinales; OC Methanosarcinaceae; Methanococcoides. OX NCBI_TaxID=259564; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RA Copeland A., Lucas S., Lapidus A., Barry K., Detter J.C., RA Glavina del Rio T., Hammon N., Israni S., Dalin E., Tice H., RA Kadner K., Aerts A., Dehal P., Pitluck S., Martinez M., Schmutz J., RA Larimer F., Land M., Hauser L., Kyrpides N., Anderson I., RA Franzmann P., Thomas T., Saunders N., Cavicchioli R., Sowers K., RA Richardson P.; RT "Complete sequence of Methanococcoides burtonii DSM 6242."; RL Submitted (MAR-2006) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Relaxes both positive and negative superturns and CC exhibits a strong decatenase activity. The B subunit binds ATP (By CC similarity). CC -!- CATALYTIC ACTIVITY: ATP-dependent breakage, passage and rejoining CC of double-stranded DNA. CC -!- SUBUNIT: Heterotetramer of two subunits A and two subunits B (By CC similarity). CC -!- SIMILARITY: Belongs to the TOP6B family.
