RC STRAIN=A-32; TISSUE=Mycelium; RA Muenger K., Lerch K.; RT "Copper metallothionein from the fungus Agaricus bisporus: chemical RT and spectroscopic properties."; RL Biochemistry 24:6751-6756(1985). CC -!- FUNCTION: The metallothioneins are involved in the cellular CC sequestration of toxic metal ions. Binds six copper (cuprous) CC ions. CC -!- MISCELLANEOUS: The absorption, luminescent, and stereoptical CC properties of the copper MT are attributed to the metal-thiolate CC complex because they are not present in the apoprotein. CC -!- SIMILARITY: Belongs to the metallothionein superfamily. Type 8 CC family. CC -------------------------------------------------------------------------- CC This Swiss-Prot entry is copyright.
