Backbone and sidechain resonance assignments and secondary structure of Scc4 from Chlamydia trachomatis.

ABSTRACT: Chlamydia trachomatis is an obligate intracellular bacterium that causes the most common sexually transmitted bacterial diseases in the world. With a biphasic developmental cycle, the bacteria utilize a type III secretion system (T3SS) to invade host cells as infectious elemental bodies, which then differentiate into actively dividing reticulate bodies. The regulation of the developmental cycle and the T3SS are linked by the bi-functional protein, specific Chlamydia chaperone 4 (Scc4). Scc4 is a class I T3SS chaperone forming a heterodimer with specific Chlamydia chaperone 1 (Scc1) to chaperone the essential virulence effector, Chlamydia outer membrane protein N. Scc4 also functions as a transcription factor by binding to the RNA polymerase holoenzyme between the flap region of the β subun
