Abstract: A process is described wherein there is added to an acidic environment, which contains at least one protein, a block-wise enzymatically de-esterified pectin, and wherein the pectin is a high ester pectin. Also described is a recombinant pectin methyl esterase.

Abstract: A process for modifying a pectin comprising providing a host having PME activity and PG activity; transforming said host by silencing PG activity thereby to provide an increased PME to PG ratio; preparing a PME extract from the transformed host; using the PME extract to modify pectin.

Abstract: A process is described wherein there is added to an acidic environment, which contains at least one protein, a block-wise enzymatically de-esterified pectin, and wherein the pectin is a high ester pectin. Also described is a recombinant pectin methyl esterase.

Abstract: A composition suitable for use as a foodstuff or in the preparation of a foodstuff is described. The composition includes a pectin methyl esterase (PME); a first PME substrate; and a second PME substrate; wherein neither the first PME substrate nor the second PME substrate originates in situ from the other.

Abstract: A composition suitable for use as a foodstuff or in the preparation of a foodstuff is described. The composition comprises a pectin methyl esterase (“PME”); a first PME substrate; and a second PME substrate; wherein neither the first PME susbtrate nor the second PME substrate originates in situ from the other.

Abstract: The present invention provides a method for identifying or selecting from a population of eukaryotic cells cultivated on or in a medium containing at least one compound, cells which have a metabolic advantage as a result of having being transformed, wherein:i) the cells are transformed with a nucleotide sequence or a co-introduced nucleotide sequence one of which comprises a region which: (a) encodes a protein which is involved in the metabolism of the compound, and/or (b) regulates the activity of the protein; andii) the compound is mannose or xylose or a derivative or a precursor of these, or a substrate of the protein, or is capable of being metabolized by the transformed cells into such a substrate, with the proviso that the compound is not mannose when the protein is mannose 6 phosphate isomerase.
