an artificial gene construct for a protein homologous to phosphatidylinositol phosphate synthase of Mycobacterium tuberculosis and archaetidylinositol phosphate synthase of Methanothermobacter thermautotrophicus is cloned in Escherichia coli and introduced into Homo sapiens cells. The recombinant cells do not show phosphatidylinositol phosphate synthase or archaetidylinositol phosphate synthase activities. Phosphatidylinositol synthase and archaetidylinositol synthase activities are determined, 7 pmol/h/mg and 2 pmol/h/mg, respectively |

an artificial gene construct for a protein homologous to phosphatidylinositol phosphate synthase of Mycobacterium tuberculosis and archaetidylinositol phosphate synthase of Methanothermobacter thermautotrophicus is cloned in Escherichia coli and introduced into Saccharomyces cerevisiae cells. The recombinant cells do not show phosphatidylinositol phosphate synthase or archaetidylinositol phosphate synthase activities. Phosphatidylinositol synthase and archaetidylinositol synthase activities are determined, 107 pmol/h/mg and 7 pmol/h/mg, respectively |

2.7.8.11 | more |
generation of transgenic maize constitutively overexpressing or underexpressing gene ZmPIS, encoding PIS from maize, under the control of a maize ubiquitin promoter. Lipid profiling analysis shows that, under drought stress conditions, the overexpression of ZmPIS in maize results in significantly elevated levels of most phospholipids and galactolipids in leaves compared with those in wild-type plants, analysis of expression pattern of genes involved in the phospholipid metabolism pathway and drought response, phenotype, overview. Sense transgenic plants are more tolerant to drought stress at the pre-flowering stage and retain more solutes and water under drought stress conditions |

2.7.8.11 | Hy3 |
hybrid construct of 57 N-terminal amino acids from Saccharomyces cerevisiae PIS and 159 C-terminal amino acids from PfPIS, no in vitro activity, 60% complementation of in vivo activity in yeast lacking endogenous PIS gene compared to ScPIS complementation efficiency (100%) |
