Zusammenfassung:A fragment of DNA (Fig. 7) obtained from a bacterium of the genus Pseudomonas containing the coding gene for the isoamylase enzyme is novel. Also novel are replicable recombinant DNA molecules for expression in host micro-organisms containing the aforementioned DNA fragment or coding regions thereof for mature isoamylase or for a polypeptide having biological activity equivalent to that of isoamylase. Also novel are host micro-organisms transformed by the aforementioned molecules of recombinant DNA capable of expressing and/or secreting the mature isoamylase enzyme or a polypeptide having a biological activity equivalent to that of isoamylase. The resulting isoamylase is specified in terms of aminoacid sequence, structure and biological activity.
