| 摘要 |
This invention relates to newly identified polynucleotides and polypeptides in the phytic acid biosynthetic pathways, variants and derivatives of the same; methods for making the polynucleotides, polypeptides, variants, derivatives and antagonists. In particular, the invention relates to polynucleotides encoding inositol polyphosphate 2-kinase (IPP2-K) and polypeptides exhibiting such activity to modulate the phytic acid biosynthesis in such a way as to decrease phytic acid and/or increase the non-phytic acid phosphorous, especially in corn or soy animal feedstuffs. |
