Described are methods for the production of isobutene comprising the enzymatic conversion of 3-methylcrotonic acid into isobutene wherein said 3-methylcrotonic acid is obtained by the enzymatic conversion of 3-methylcrotonyl-CoA into 3-methylcrotonic acid or wherein said 3-methylcrotonic acid is obtained by the enzymatic conversion of 3-hydroxyisovalerate (HIV) into 3-methylcrotonic acid. It is described that the enzymatic conversion of 3-methylcrotonic acid into isobutene can, e.g., be achieved by making use of a 3-methylcrotonic acid decarboxylase, preferably an FMN-dependent decarboxylase associated with an FMN prenyl transferase, an aconitate decarboxylase (EC 4.1.1.6), a methylcrotonyl-CoA carboxylase (EC 6.4.1.4), or a geranoyl-CoA carboxylase (EC 6.4.1.5).

Embodiments of the present invention relate to methods for the biosynthesis of di- or trifunctional C7 alkanes in the presence of isolated enzymes or in the presence of a recombinant host cell expressing those enzymes. The di- or trifunctional C7 alkanes are useful as intermediates in the production of nylon-7, nylon-7,x, nylon-x,7, and polyesters.
