摘要：
The invention relates to a variant polypeptide having lactase activity. The invention also relates to a nucleic acid sequence encoding such a variant polypeptide, to a nucleic acid construct comprising said nucleic acid sequence, to a recombinant expression vector comprising said nucleic acid construct and to a recombinant host cell comprising said expression vector. Further, the invention relates to a method for producing a lactase variant via use of such a host cell. Also, the invention relates to a method of producing a lactase polypeptide variant. The invention further relates to a composition comprising a lactase variant, to use of such a lactase variant or to the use of a lactase variant-containing composition in the preparation of a dairy product, to a process for the production of a dairy product and to the resulting dairy product.
