Expression control sequences

摘要

Expression control sequences are provided for the expression of pro- and eukaryotic proteins. These control sequences are produced by combining promoter sequences having a low signal strength and a high in vivo promoter strength and operator/repressor systems having a high association rate. Expression vectors containing such expression control sequences, microorganisms transformed with such expression vectors and methods for producing pro- and eukaryotic proteins using the expression control sequences, expression vectors and transformed microorganisms are also provided.
