Structural insights into the main S-layer unit of Deinococcus radiodurans reveal a massive protein complex with porin-like features
D Farci, MA Aksoyoglu, SF Farci, JA Bafna… - Journal of Biological …, 2020 - ASBMB
In the extremophile bacterium Deinococcus radiodurans, the outermost surface layer is
tightly connected with the rest of the cell wall. This integrated organization provides a
compact structure that shields the bacterium against environmental stresses. The
fundamental unit of this surface layer (S-layer) is the S-layer deinoxanthin-binding complex
(SDBC), which binds the carotenoid deinoxanthin and provides both, thermostability and UV
radiation resistance. However, the structural organization of the SDBC awaits elucidation …
