A protein scaffold includes a plurality of EutM subunits and a multi-enzyme cascade. The multi-enzyme cascade includes a first enzyme attached to the first EutM subunit and a second enzyme attached to the second EutM subunit. The scaffold may be formed by a method that generally includes incubating a plurality of EutM subunits under conditions allowing the EutM subunits to self-assemble into a protein scaffold, attaching a first enzyme of a multi-enzyme cascade to a first EutM subunit, and attaching a second enzyme of the multi-enzyme cascade to a second EutM subunit. The scaffold may be self-assembled in vivo or in vitro. Each enzyme may be, independently of any other enzyme, attached to its EutM subunit in vivo or in vitro. Each enzyme may be, independently of any other enzyme, attached to its EutM subunit before or after the scaffold is assembled.

The present invention generally relates to the microbiological industry, and specifically to the production of L-serine or L-serine derivatives using genetically modified bacteria. The present invention provides genetically modified microorganisms, such as bacteria, wherein the expression of genes encoding for enzymes involved in the degradation of L-serine is attenuated, such as by inactivation, which makes them particularly suitable for the production of L-serine at higher yield. The present invention also provides means by which the microorganism, and more particularly a bacterium, can be made tolerant towards higher concentrations of serine. The present invention also provides methods for the production of L-serine or L-serine derivative using such genetically modified microorganisms.

Described herein are recombinant host organisms expressing a sugar transporter and an active pentose fermentation pathway. Also described are processes for producing a fermentation product, such as ethanol, from starch or cellulosic-containing material with the recombinant host organisms.

The invention provides a polypeptide comprising a phosphate translocator and a microbial membrane-integrating protein. The phosphate translocator may be a plastidic phosphate translocator and the membrane-integrating protein may be derived from Bacillus subtilis. The invention also provides a bacterium genetically modified to export phosphorylated compounds; such organism may contain the polypeptide of the invention and may be further modified to decrease the metabolism of phosphorylated compounds or increase the production of phosphorylated compounds. Also provided is a method for the manufacture of phosphorylated compounds, comprising culturing a bacterium according to the invention and extracting the phosphorylated compounds from the culture medium. The method may be for the manufacture of dihydroxyacetone phosphate (DHAP), and optionally, may include the further step of converting the DHAP into methylglyoxal.
