LITERATURE
dimer
-
2 * 45800, the enzyme is always present as a dimer regardless of the added cofactor, in the case of Mg2+, the dimeric protein possesses the largest volume (93800 Da), most likely due to a more relaxed conformation. With Co2+, the enzyme seems to have a more compact conformation (87600 Da), which may be responsible for the change in product spectrum calculated from sequence
heterodimer
homodimer
-
-
homotetramer
tetramer
-
enzyme forms a heterotetramer of two catalytic large plus two regulatory small subunits, crystallization data.
