2.1.1.217 monomer BsTrmK is active as a monomer, the higher oligomeric states of BsTrmK are formed via disulphide bonds involving the two cysteines in BsTrmK sequence at positions 35 and 152. Such bonds can be broken by addition of a reducing-agent, and addition of DTT to the MTase reaction buffer results in a dramatic increase of the enzymatic activity -, 757861 2.1.1.217 monomer Sp1610 exists as a monomer both in solution and in the P212121 crystal 713478 2.1.1.217 additional information backbone 1H, 15N and 13C chemical shift assignments of TrmK from Bacillus subtilis obtained by heteronuclear multidimensional NMR spectroscopy as well as its secondary structure in solution, overview -, 756149 2.1.1.217 additional information BsTrmK consists of an N-terminal Class I MTase domain linked to a C-terminal coiled-coil domain, structure comparisons, overview -, 757861
