摘要:
5-hydroxytryptophan (5-HTP), a precursor of serotonin, is produced in a microbial host cell. A modified bacterial phenylalanine 4-hydroxylase (P4H) catalyzes the tryptophan 5-hydroxylation reaction. Optionally the host cell includes a cofactor regeneration mechanism, allowing continuous production of 5-HTP without supplementation of exogenous cofactors.
摘要:
Recombinant microbial cells and methods for producing 5HTP, melatonin and related compounds using such cells are described. More specifically, the recombinant microbial cell may comprise exogenous genes encoding one or more of an L-tryptophan hydroxylase, a 5-hydroxy-L-tryptophan decarboxylyase, a serotonin acetyltransferase, an acetylserotonin O-methyltransferase; and means for providing tetrahydrobiopterin (THB), and can be further genetically modified to enrich one or more of tryptophan, S-adenosyl-L-methinonine and acetyl coenzyme A. Related sequences and vectors for use in preparing such recombinant microbial cells are also described.

摘要:
The present invention provides a method of treatment for cancer in a subject comprising the administration of a prodrug, wherein the subject is colonised with an obligate anaerobic microorganism capable of expressing a polypeptide having nitroreductase activity, wherein the polypeptide exhibits preferential reduction of CB1954 to a 4-hydroxylamine (4HX) derivative instead of a 2-hydroxylamine derivative; and is capable of reducing CB1954 to the 4HX derivative with a Km of less than 30 micromolar. The present invention further provides an isolated polypeptide, nucleic acids encoding said polypeptide, vectors and host cells comprising said nucleic acids and vectors and uses of the above in treating solid tumours.
