    Abstract: The present invention features improved processes and organisms for the production of methionine. The invention demonstrates that a .DELTA.metF organism or a .DELTA.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.EPSILON. 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 .DELTA.metF .DELTA.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: Use of a nucleic acid (I) with promoter activity for transcribing genes, where (I) is (a) a 173 nucleotide sequence (SEQ ID No.:1); (b) a variant of (SEQ ID No.:1) with at least 90% identity and derived by substitution, insertion or deletion of nucleotides; (c) a sequence that hybridizes to (SEQ ID No.:1) under stringent conditions; or (d) a functionally equivalent fragment of (a)-(c), is new. Independent claims are also included for: (1) use of an expression unit (EU), containing (I) and functionally linked to a sequence (X) that ensures translation of RNA, for expressing genes; (2) (I), other than sequence (SEQ ID No.:1), i.e. (Ia), as new compounds; (3) EU that contain (Ia) linked to (X); (4) altering (or producing) the transcription rate of genes in a microorganism, relative to the wild type; (5) expression cassette (EC) comprising at least one EU of (SEQ ID No.:1), at least one other nucleic acid sequence (to be expressed) and optionally additional gene control elements, where at least the first two are linked and the sequence being expressed is heterologous with respect to EU; (6) expression vector (EV) that contains EC; (7) genetically modified microorganisms (GMO) having, for at least one gene, an altered (or induced) transcription rate, relative to the wild type; (8) preparing biosynthetic products by culturing GMO of (7); (9) use of the sequence gaaagga (SEQ ID No.:44) as a ribosome-binding site in expression units that provide expression of genes in Corynebacterium or Brevibacterium; (10) use of the sequences tgcaat (SEQ ID No.:42) and tatcatt (SEQ ID No.:43) as -10 regionS for expression of genes in Corynebacterium or Brevibacterium; and (11) expression units that contain sequences (SEQ ID No.:42) - (SEQ ID No.:44).

    Abstract: Use, for transcribing genes, of a nucleic acid (I) with promoter activity, where (I) is a 186 base pair sequence (1), reproduced; a variant of (1) with at least 90% identity and derived by substitution, insertion or deletion of nucleotides; a sequence that hybridizes to (1) under stringent conditions; or a functionally equivalent fragment of them, is new. Independent claims are also included for the following: (1) use of an expression unit (EU), containing (I) and functionally linked to a sequence (X) that ensures translation of RNA, for expressing genes; (2) (I), other than sequence (1), i.e. (Ia), as new compounds; (3) EU that contain (Ia) linked to (X); (4) altering (or producing) the transcription rate of genes in a microorganism, relative to the wild type; (5) expression cassette (EC) comprising at least one EU of (1), at least one other nucleic acid sequence (to be expressed) and optionally additional gene control elements, where at least the first two are linked and the sequence being expressed is heterologous with respect to EU; (6) expression vector (EV) that contains EC; (7) genetically modified microorganisms (GMO) having, for at least one gene, an altered (or induced) transcription rate, relative to the wild type; (8) preparing biosynthetic products by culturing GMO of (7); (9) use of the sequence aggagga (42) as a ribosome-binding site in expression units that provide expression of genes in Corynebacterium or Brevibacterium; (10) use of the sequences tagttt (39), taggat (40) or tgcgct (41) as -10 regions for expression of genes in Corynebacterium or Brevibacterium; and (11) expression units that contain sequences (39)-(42).
