摘要：

A cadmium inducible metal-binding protein has been isolated from cadmium exposed Synechococcus sp. blue-green algae. Amino acid analysis indicated a high half-cystine concentration and an apparent minimum molecular weight of 8100. The isoelectric point was determined to be 4.3. Together with electrochemical characteristics these findings constitute the first conclusive evidence for the existence of metallothionein in a prokaryotic organism. © 1979.
