Fuente: WIPO "dairy products" The invention provides modified dairy proteins in which at least one potentially phosphorylated amino acid has been replaced with a negatively charged amino acid. The modified dairy proteins exhibit at least one of: an improved capacity to binding calcium, an improved capacity to form a micelle, an altered isoelectric point (pI), altered thermal stability and an altered zeta potential, when expressed in a heterologous expression system, relative to that of the unmodified dairy protein when it is recombinantly expressed in the same heterologous expression system. The invention also provides cells, tissues, plants, plant parts and seeds, expressing the modified dairy proteins. The invention also provides methods for the production and use of the modified proteins. The invention also provides food or beverage products or ingredients comprising the modified dairy proteins.
