Engineering a palette of eukaryotic chromoproteins for bacterial synthetic biology

Abstract

Availability of 14 engineered CP genes compared in <i>E. coli</i>, together with chromosomal mutants suitable for competition assays, should simplify and expand CP study and applications. There was no single plasmid-borne CP that combined all of the most desirable features of intense color, fast maturation and low fitness cost, so this study should help direct future engineering efforts.
