Comments "MalK, the nucleotide-binding component of the maltose permease, has been purified via a denaturation-renaturation of inclusion bodies (22) it has a turnover rate of 0.9s^-1 (calculated from Ref. 33 [PMID 8360157], assuming that it functions as a monomer) and an affinity for ATP of 70 µM, both of which are comparable to those of HisP(his6)."
