sequence The residue numbering scheme for this structure follows that of the E. coli enzyme. This ...sequence The residue numbering scheme for this structure follows that of the E. coli enzyme. This treatment results in a break in the sequential numbering in a couple of places.
This protein forms a crystallographic dimer and is not known to be a dimer in solution. The second monomer can be generated by the following symmetry operations: -y, x-y, z+1/3 and -x+y, -x, z+2/3 and -x, -y, z+1/2 and y, -x+y, z+5/6 and x-y, x, z+1/6.
