Structural characterization of distinct alpha3N and alpha5 metal sites in the cyanobacterial zinc sensor SmtB.
VanZile ML, Chen X, Giedroc DP. VanZile ML, et al. Among authors: chen x. Biochemistry. 2002 Aug 6;41(31):9765-75. doi: 10.1021/bi0201771. Biochemistry. 2002. PMID: 12146942
Both sites are characterized by similar affinities for Co(II) (K(Co) approximately equal to 2-5 x 10(9) M(-1)), while the Zn(II) affinities are at least 20-fold different (K(Zn)(alpha)(3N) > or = 10(13) M(-1); K(Zn)(alpha)(5) approximately equal to 5 x 10(11) M(- …
