The present invention relates to novel esterase, more particularly to esterase variants having improved thermostability compared to the esterase of SEQ ID N1 and the uses thereof for degrading polyester containing material, such as plastic products. The esterases of the invention are particularly suited to degrade polyethylene terephthalate, and material containing polyethylene terephthalate.

Esterases and uses thereof

The present invention relates to novel esterase, more particularly to esterase variants having improved thermostability compared to the esterase of SEQ ID No 1 and the uses thereof for degrading polyester containing material, such as plastic products. The esterases of the invention are particularly suited to degrade polyethylene terephthalate, and material containing polyethylene terephthalate.

A method of producing 2,4-dihydroxybutyric acid (2,4-DHB) by a synthetic pathway that includes transforming malate into 4-phospho-malate using a malate kinase, then transforming 4-phospho-malate into malate-4-semialdehyde using a malate semialdehyde dehydrogenase, and then transforming malate-4-semialdehyde into 2,4-DHB using a DHB dehydrogenase.

Method of production of 2,4-dihydroxybutyric acid

A method of producing 2,4-dihydroxybutyric acid (2,4-DHB) by a synthetic pathway that includes the transforming malate in 4-phospho-malate using a malate kinase, said 4-phospho-malate being transformed in malate-4-semialdehyde using a malate semialdehyde dehydrogenase and said malate-4-semialdehyde being transformed in 2,4-DHB using a DHB dehydrogenase.
