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 said isobutene; (B) wherein said recombinant organism or microorganism has an increased pool of coenzyme A (CoA) over the organism or microorganism from which it is derived due to: (i) an increased uptake of pantothenate; and/or (ii) an increased conversion of pantothenate into CoA. Moreover, described is the use of such a recombinant organism or microorganism for the production of isobutene. Further, described is a method for the production of isobutene by culturing such a recombinant organism or microorganism in a suitable culture medium under suitable conditions.

A method for producing isoprene glycol, including: enzymatically generating 3-hydroxy-3-methylbutyryl-CoA (HMB-CoA) from acetyl-CoA (Ac-CoA); enzymatically generating 3-methyl-3-hydroxybutyrylaldehyde (3-HMBA) from HMB-CoA; and enzymatically converting 3-HMBA to isoprene glycol (ISPG). Wherein the enzymatically generating 3-HMBA from HMB-CoA includes: enzymatically reducing HMB-CoA to produce 3-HMB; or enzymatically hydrolyzing HMB-CoA to 3-hydroxy-3-methylbutyric acid (HMB) and then enzymatically reducing HMB to 3-HMBA. Also provided herein are an enzyme composition, a nucleic acid composition, and a transgenic microorganism for producing isoprene glycol.
