Structural mechanism of nuclear membrane sealing by LEM2-ESCRT-III

In open mitosis, re-establishing nucleocytoplasmic compartmentalization requires the LEM2-ESCRT machinery to coordinate spindle clearance with sealing of the remaining nuclear envelope pores. The structural basis of this topologically unique and fundamental membrane-remodeling process is poorly understood. Here, we com...

Structural basis of sulfide production in dissimilatory sulfur metabolism

High-resolution cryo-EM structures of DsrMKJOP from Archaeoglobus fulgidus are presented, alone, with menadiol and with the sulfur-carrying substrate DsrC-trisulfide, complemented by physiological and biochemical studies to clarify how SRM control the reactivity of sulfur to selectively achieve sulfide production.
