This document provides butyrylcholinesterases having an enhanced ability to hydrolyze acyl ghrelin as well as nucleic acids encoding such butyrylcholinesterases. This document also provides methods and materials for treating obesity and/or aggression. For example, methods for administering a nucleic acid encoding a wild-type or mutant butyrylcholinesterase having the ability to hydrolyze acyl ghrelin to a mammal under conditions wherein the level of acyl ghrelin within the mammal is reduced, under conditions wherein the rate of body weight gain of the mammal is reduced, under conditions wherein the mammal's level of aggression is reduced, and/or under conditions wherein the mammal's rate of developing stress-induced tissue damage are provided.
A method for reducing the body weight of a mammal, wherein said method comprises administering nucleic acid encoding a polypeptide to said mammal, wherein said polypeptide comprises the amino acid sequence set forth in SEQ ID NO:3 comprising an F329M substitution and optionally one or more additional amino acid substitutions selected from the group consisting of A199S, F227A, S287G, A328W, and Y332G with the numbering starting after the signal sequence of SEQ ID NO:3, and wherein said polypeptide has an increased ability to hydrolyze acyl ghrelin as compared to a polypeptide having the amino acid sequence set forth in SEQ ID NO:3, and wherein the body weight of said mammal is reduced following said administration.
