    Abstract: The present invention features improved processes and organisms for the production of methionine. The invention demonstrates that a ?metF organism or a ?metE AmetH organism, for example, mutants of C. glutamicum or E. coli, can use a methyl capped sulfide source, e.g., dimethyl disulfide (DMDS), as a source of both sulfur and a methyl group, bypassing the need for MetH/Met? and MetF activity and the need to reduce sulfate, for the synthesis of methionine. Also described in this patent are data implicating MetY (also called MetZ) as an enzyme that incorporates a methyl capped sulfide source, e.g., DMDS, into methionine. A ?metF ?metB strain of C. glutamicum can use a methyl capped sulfide source, e.g., DMDS, as a source of both sulfide and a methyl group. Furthermore, methionine production by engineered prototrophic organisms that overproduce O-acetyl-homoserine was improved by the addition of a methyl capped sulfide source, e.g., DMDS.

    Abstract translation: 本发明的特征在于用于生产甲硫氨酸的改进方法和生物体。 本发明证明，metF生物体或αmetE AmetH生物体，例如谷氨酸棒状杆菌或大肠杆菌的突变体可以使用甲基封端的硫化物源，例如二甲基二硫（DMDS）作为硫的来源 和甲基，绕过MetH / Met？ 和MetF活性以及减少硫酸盐的需要，用于合成甲硫氨酸。 该专利中还描述了涉及MetY（也称为MetZ）的数据，其作为将甲基封端的硫化物源（例如DMDS）并入甲硫氨酸中的酶。 谷氨酸棒状芽孢杆菌的ΔFIFFmetB菌株可以使用甲基封端的硫化物源，例如DMDS，作为硫化物和甲基两者的来源。 此外，通过加入甲基封端的硫化物源（例如DMDS），改善过度产生O-乙酰高丝氨酸的工程化原养殖生物体的甲硫氨酸生产。

    Abstract: The present invention features improved processes and organisms for the production of methionine. The invention demonstrates that a &Dgr;metF organism or a &Dgr;metE AmetH organism, for example, mutants of C. glutamicum or E. coli, can use a methyl capped sulfide source, e.g., dimethyl disulfide (DMDS), as a source of both sulfur and a methyl group, bypassing the need for MetH/MetE and MetF activity and the need to reduce sulfate, for the synthesis of methionine. Also described in this patent are data implicating MetY (also called MetZ) as an enzyme that incorporates a methyl capped sulfide source, e.g., DMDS, into methionine. A &Dgr;metF &Dgr;metB strain of C. glutamicum can use a methyl capped sulfide source, e.g., DMDS, as a source of both sulfide and a methyl group.

    Abstract: The present invention features methods of increasing the production of a fine chemical, e.g., lysine from a microorganism, e.g., Corynebacterium by way of deregulating an enzyme encoding gene, i.e., lactate dehydrogenase. In a preferred embodiment, the invention provides methods of increasing the production of lysine in Corynebacterium glutamicum by way of the expression of lactate dehydrogenase activity. The invention also provides a novel process for the production of lysine by way of regulating carbon flux towards oxaloacetate (OAA). In a preferred embodiment, the invention provides methods for the production of lysine by way of utilizing fructose or sucrose as a carbon source.
