DNA COMPOUNDS COMPRISING SEQUENCES ENCODING MANNURONAN C-5-EPIMERASE

摘要

DNA compounds encompassing sequences coding for enzymes having mannuronan C-5-epimerase activity are disclosedand a process for the preparation of such enzymes. The genetic sequences andenzymes prepared may be used in the productionof alginates having a definite G/M ratio and block structure. Alginates havinga definite G/M ratio may also be produced byselective inactivation of the genetic sequences.
