    • The invention provides a non-naturally occurring microbial organism having an acetyl- CoA pathway and the capability of utilizing syngas or syngas and methanol. In one embodiment, the invention provides a non-naturally occurring microorganism, comprising one or more exogenous proteins conferring to the microorganism a pathway to convert CO, CO 2 and/or H 2 to acetyl-coenzyme A (acetyl-CoA), methyl tetrahydro folate (methyl-THF) or other desired products, wherein the microorganism lacks the ability to convert CO or CO 2 and H 2 to acetyl- CoA or methyl-THF in the absence of the one or more exogenous proteins. For example, the microbial organism can contain at least one exogenous nucleic acid encoding an enzyme or protein in an acetyl-CoA pathway. The microbial organism is capable of utilizing synthesis gases comprising CO, CO 2 and/or H 2 , alone or in combination with methanol, to produce acetyl- CoA. The invention additionally provides a method for producing acetyl-CoA, for example, by culturing an acetyl-CoA producing microbial organism, where the microbial organism expresses at least one exogenous nucleic acid encoding an acetyl-CoA pathway enzyme or protein in a sufficient amount to produce acetyl-CoA, under conditions and for a sufficient period of time to produce acetyl-CoA.
    • 本发明提供了具有乙酰辅酶A途径和利用合成气或合成气和甲醇的能力的非天然存在的微生物。 在一个实施方案中,本发明提供非天然存在的微生物,其包含一种或多种外源蛋白质,赋予微生物将CO,CO 2和/或H 2转化为乙酰辅酶A(乙酰辅酶A),甲基四氢叶酸( 甲基-THF)或其它所需产物,其中微生物缺乏在不存在一种或多种外源蛋白的情况下将CO或CO 2和H 2转化为乙酰辅酶A或甲基-THF的能力。 例如,微生物生物体可以含有至少一种编码乙酰辅酶A途径中的酶或蛋白质的外源核酸。 微生物生物能够单独或与甲醇组合使用包含CO,CO 2和/或H 2的合成气体,以产生乙酰辅酶A。 本发明另外提供了生产乙酰辅酶A的方法,例如通过培养产生乙酰辅酶A的微生物,其中微生物生物体表达至少一种编码乙酰辅酶A途径酶或蛋白质的外源核酸,其量足够 在条件和足够的时间内产生乙酰辅酶A产生乙酰辅酶A。
