标题 :Methods and microorganisms for increasing the biological synthesis of difunctional alkanes
发明人：LAU MAN KIT
权利人:BIOAMBER INC
摘要:A method of increasing the production a difunctional alkane in a microorganism that produces a difunctional alkane from alpha-keto acid by increasing the production of homocitrate in the cell relative to a wild-type or parent cell. The production of homocitrate may be obtained by engineering pathways that increase the production of alpha-ketoacid, such as alpha-ketoglutarate.

摘要:The present invention features improved processes and organisms for the production of methionine. The invention demonstrates that a ΔmetF organism or a ΔmetE 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 ΔmetF ΔmetB 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.

摘要:A method is useful for the biocatalytic synthesis of proteinogenic L-amino acids, such as L-alanine, L-valine, L-methionine, L-leucine, L-isoleucine or L-phenylalanine from a respective aldehyde and carbon dioxide. In particular, the method is useful for the biocatalytic synthesis of L-methionine from 3-methylthio-propanal (“methionalâ€?) and carbon dioxide.
