摘要 |
PCT No. PCT/NO93/00151 Sec. 371 Date May 9, 1995 Sec. 102(e) Date May 9, 1995 PCT Filed Oct. 8, 1993 PCT Pub. No. WO94/09124 PCT Pub. Date Apr. 28, 1994DNA compounds encompassing sequences coding for enzymes having mannuronan C-5-epimerase activity are disclosed and a process for the preparation of such enzymes. The genetic sequences and enzymes prepared may be used in the production of alginates having a definite G/M ratio and block structure. Alginates having a definite G/M ratio may also be produced by selective inactivation of the genetic sequences. |
