Shape memory polymers and copolymers are based on poly(hydroxyalkanoates) (PHA) and have improved elastomeric properties. The shape memory polymers and copolymers may be used as protective, reinforcement, cladding or embellishment material having mechanical properties enabling substitution to materials based on technical polymers such as plasticized PVC and polyolefins.

The subject invention concerns materials and methods for alkene reduction of compounds, such as levoglucosenone (LGO) and (S)-&#x3b3;-hydroxymethyl-&#x3b1;,&#x3b2;-butenolide (HBO), using an alkene reductase enzyme. In one embodiment, a method of the invention comprises alkene reduction of a target compound by reacting the compound with an Old Yellow Enzyme (OYE) that reduces alkene bonds. In one embodiment, the OYE is OYE 2.6 fromand comprises the amino acid sequence of SEQ ID NO: I. In a specific embodiment, the enzyme is an Old Yellow Enzyme (OYE) 2.6 mutant having an amino acid substitution at position 78 in the sequence, wherein the tyrosine at position 78 is substituted with a tryptophan amino acid (Y78W) and is designated as OYE 2.6 Y78W (SEQ ID NO:2).

A phenol polymer is obtainable by oligomerization of one or more macropolyphenols serving as monomers, wherein the oligomerization step is catalyzed by an oxidase enzyme. The bonds between the macropolyphenol fragments in the polymer are exclusively 5,5-biaryl bonds. This polymer is useful as an antioxidant, chelating agent, plasticizing agent, or antimicrobial agent.
