    摘要: The instant disclosure teaches transposons and methods of the instant invention for making Protein Fusions by rapid, random shuffling of protein domains to produce novel protein fusions. This system is generally applicable to production of multifunctional chimeric proteins in vivo and in vitro. The methods and constructs of the instant invention can be used to randomly create both carboxy- and amino-terminal protein fusions in vivo. The methods and contructs of the instant invention are useful in the development of a protein domain library, in the construction of multifunctional enzymes, and in the accelerated evolution of new enzymatic activities.

    摘要: A gene encoding spinach acyl carrier protein-I-Gly.sup.76 (ACP-I) was fused to a gene encoding the F.sub.c -binding portion of staphylococcal protein A. The gene fusion can be expressed in E. coli thereby resulting in the production of an appropriately sized protein possessing ACP activity in acyl ACP synthetase reactions, plant MCT reactions, and plant fatty acid synthesis. This gene fusion, under the control of the .lambda.P.sub.R promoter, expresses high levels of a 42 kDa fusion protein in E. coli. This protein functions as a affinity moiety in purification methods for the isolation of enzymes involved in fatty acid synthetase, acyl ACP synthetase and malonyl-CoA:ACP tranacylase reactions.
