Zx. Huang et al., STUDY ON MODEL CLUSTERS OF METALLOTHIONEIN - STRUCTURE AND ITS KINETICS OF ZINC TRANSFER-REACTION TO APO-CARBONIC ANHYDRASE, Journal of inorganic biochemistry, 54(2), 1994, pp. 147-155
In order to investigate the relationship between the structure and fun
ctions of metallothioneins, [(CH3)(4)N](2)[Zn-4(SC6H5)(10)], as a mode
l cluster of metallothionein has been synthesized. The structure of th
e model cluster has been examined by a CAD-4 x-ray diffractometer and
the kinetics of zinc transfer reaction to apocarbonic anhydrase has be
en studied. Structural analysis and kinetic study show that compared w
ith the model cluster the clusters in metallothionein are structurally
more loose and they have a similar reactivity of zinc transfer.
