ERRγ-DBD undergoes dimerization and conformational rearrangement upon binding to the downstream site of the DR1 element.

The estrogen-related receptor (ERR) family members are reported to bind DNA elements as either monomer or dimer. However, to date, only one solution NMR structure of ERRβ in complex with a half-site DNA element has been reported. To better understand the DNA regulation mechanism, we determined the crystal structure of ERRγ-DBD bound to a natural DR1 element in Pla2g12b promoter to 2.

Substrate-induced dimerization of elaiophylin glycosyltransferase reveals a novel self-activating form of glycosyltransferase for symmetric glycosylation.

Elaiophylin (Ela), a unique 16-membered symmetric macrodiolide antibiotic, displays broad biological activity. Two rare 2-deoxy-L-fucose moieties at the ends of Ela are critical for its activity. Previously, elaiophylin glycosyltransferase (ElaGT) was identified as the enzyme that is responsible for the symmetric glycosylation of Ela, acting as a potential enzymatic tool for enhancing the diversity and activity of Ela.
