摘要： The present invention provides the field of enhancing proteins and in particular to that of proteins enhanced by molecular change. It provides a variant of a phytase that is termed enhanced in that is has better thermostability and/or activity than the original phytase. The invention also provides a nucleic acid coding for said variant, a cassette or an expression vector containing said variant, a host cell expressing said variant, a composition comprising said variant and uses thereof, principally in the preparation of food additives and animal feed.
