  • Patent number: 11773421
    Abstract: Described is a method for the production of fructose-6-phosphate (F6P) from dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate (G3P) comprising the steps of: (a) enzymatically converting dihydroxyacetone phosphate (DHAP) into dihydroxyacetone (DHA); and (b) enzymatically converting the thus produced dihydroxyacetone (DHA) and glyceraldehyde-3-phosphate (G3P) into fructose-6-phosphate (F6P); or comprising the steps of: (a?) enzymatically converting glyceraldehyde-3-phosphate (G3P) into glyceraldehyde; and (b?) enzymatically converting the thus produced glyceraldehyde together with dihydroxyacetone phosphate (DHAP) into fructose-1-phosphate (F1P); and (c?) enzymatically converting the thus produced fructose-1-phosphate (F1P) into fructose-6-phosphate (F6P).

  • Publication number: 20220145336
    Abstract: Described is a recombinant organism or microorganism which is capable of enzymatically converting acetyl-CoA into isobutene, (A) wherein in said organism or microorganism: (i) acetyl-CoA is enzymatically converted into acetoacetyl-CoA, (ii) acetoacetyl-CoA is enzymatically converted into 3-hydroxy-3-methylglutaryl-CoA, (iii) 3-hydroxy-3-methylglutaryl-CoA is enzymatically converted into 3-methylglutaconyl-CoA, (iv) 3-methylglutaconyl-CoA is enzymatically converted into 3-methylcrotonyl-CoA, and (v) wherein said 3-methylcrotonyl-CoA is converted into isobutene by: (a) enzymatically converting 3-methylcrotonyl-CoA into 3-methylcrotonic acid which is then further enzymatically converted into said isobutene; or (b) enzymatically converting 3-methylcrotonyl-CoA into 3-hydroxy-3-methylbutyryl-CoA which is then further enzymatically converted into 3-hydroxy-3-methylbutyric acid which is then further enzymatically converted into 3-phosphonoxy-3-methylbutyric acid which is then further enzymatically converted into sai

  • Publication number: 20210277425
    Abstract: Described are methods for the production of isobutene comprising the enzymatic conversion of 3-methylcrotonic acid into isobutene wherein the enzymatic conversion of 3-methylcrotonic acid into isobutene is achieved by making use of an FMN-dependent decarboxylase associated with an FMN prenyl transferase, wherein said FMN prenyl transferase catalyzes the prenylation of a flavin cofactor (FMN or FAD) utilizing dimethylallyl phosphate (DMAP) into a flavin-derived cofactor, wherein said method further comprises providing said DMAP enzymatically by: (i) the enzymatic conversion of dimethylallyl pyrophosphate (DMAPP) into said DMAP; or (ii) a single enzymatic step in which prenol is directly enzymatically converted into said DMAP; or (iii) two enzymatic steps comprising: first enzymatically converting DMAPP into prenol; and then enzymatically converting the thus obtained prenol into said DMAP; or (iv) the enzymatic conversion of isopentenyl monophosphate (IMP) into said DMAP, or by a combination of any one of (i) t
