    • The present invention describes an approach to increase taurine or hypotaurine production in prokaryotes or eukaryotes. More particularly, the invention relates to genetic transformation of organisms with genes that encode proteins that catalyze the conversion of cysteine to taurine, methionine to taurine, cysteamine to taurine, or alanine to taurine. The invention describes methods for the use of polynucleotides that encode functional cysteine dioxygenase (CDO), cysteine dioxygenase (CDO) and sulfinoalanine decarboxylase (SAD) or glutamate decarboxylase (GAD), cysteamine dioxygenase (ADO), taurine-pyruvate aminotransferase (TPAT), TPAT and sulfoacetaldehyde acetyltransferase (SA), taurine dioxygenase (TDO) or the small (ssTDeHase) and large subunits of taurine dehydrogenase (lsTDeHase) polypeptides in plants to increase taurine, hypotaurine or taurine precursor production. The preferred embodiment of the invention is in plants but other organisms may be used. Increased taurine production in plants will enhance plant growth and development, yield, or tolerance to biotic and/or abiotic stresses and could be used as nutraceutical, pharmaceutical, or therapeutic compounds or as a supplement in animal feed.
    • 本发明描述了增加原核生物或真核生物中牛磺酸或亚牛磺酸生产的方法。 更具体地说,本发明涉及具有编码蛋白质的基因的生物体的遗传转化,所述蛋白质催化半胱氨酸转化为牛磺酸,甲硫氨酸转化为牛磺酸,半胱胺转化为牛磺酸或丙氨酸转化为牛磺酸。 本发明描述了使用编码功能性半胱氨酸双加氧酶(CDO),半胱氨酸双加氧酶(CDO)和巯基丙氨酸脱羧酶(SAD)或谷氨酸脱羧酶(GAD),半胱胺双加氧酶(ADO),牛磺酸 - 丙酮酸氨基转移酶(TPAT) TPAT和磺基乙醛乙酰转移酶(SA),牛磺酸双加氧酶(TDO)或牛磺酸脱氢酶(lsTDeHase)多肽的小亚基(ssTDeHase)以增加牛磺酸,亚牛磺酸或牛磺酸前体的产生。 本发明的优选实施方案在植物中,但也可以使用其他生物体。 植物中牛磺酸生产的增加将增强植物生长和发育,产量或对生物和/或非生物胁迫的耐受性,并可用作营养品,药物或治疗化合物或作为动物饲料的补充剂。

    • The present invention provides methods to make soluble or membrane-anchored metabolic regulators for use in prokaryotes or eukaryotes. The present invention provides methods of expressing novel protein constructs that bind to specific metabolites to control their availability in the cell. The invention utilizes bacterial periplasmic binding proteins, or domains from prokaryotic and eukaryotic proteins that are functionally similar to the bacterial periplasmic binding proteins, fused together and/or fused to a peptide that encodes a transmembrane domain. Changes in metabolite availability will result in altered metabolism or receptor activity to improve growth, yield, crop quality, or tolerance to biotic and abiotic stress.
    • 本发明提供了制备用于原核生物或真核生物的可溶性或膜锚定代谢调节剂的方法。 本发明提供了表达与特异性代谢物结合以控制其在细胞中的可用性的新型蛋白质构建体的方法。 本发明利用与编码跨膜结构域的肽融合在一起和/或融合的细菌周质结合蛋白的功能上类似的原核和真核蛋白质的细菌周质结合蛋白或结构域。 代谢物可用性的变化将导致代谢或受体活性的改变,以改善生长,产量,作物质量或对生物和非生物胁迫的耐受性。
