REDOX DRIVEN B12-LIGAND SWITCH DRIVES CARH PHOTORESPONSE

Redox driven B12-ligand switch drives CarH photoresponse

Abstract CarH is a coenzyme B12-dependent photoreceptor involved in regulating carotenoid biosynthesis.How light-triggered cleavage of the B12 Co-C bond culminates in CarH tetramer dissociation to initiate transcription remains unclear.Here, a series of crystal structures of the CarH B12-binding domain after illumination suggest formation of unfore

The development of erosion features in cuesta relief regions

The cuesta relief is characterized by high slopes, colluvial deposits and intense evolutionary dynamics, making the region especially prone to soil degradation.This study intends to identify how the relief, lithology, and soils influence the occurrence of linear erosion processes of rill erosion, ravines and gullies in the cuestas environments.For
