Concerted conformational dynamics and water movements in the ghrelin G protein-coupled receptor

There is increasing support for water molecules playing a role in signal propagation through G protein-coupled receptors (GPCRs). However, exploration of the hydration features of GPCRs is still in its infancy. Here, we combined site-specific…

Modulation of cellular fate of vinyl triarylamines through structural fine tuning: to stay or not to stay in the mitochondria?

Mitochondria is involved in many cellular pathways and dysfunctional mitochondria are linked to various diseases. Hence efforts have been driven to design mitochondria-targeted fluorophores for monitoring the mitochondria status. However, the…

Crystal structures of N-terminally truncated telomerase reverse transcriptase from fungi

Telomerase plays critical roles in cellular aging, in the emergence and/or development of cancer, and in the capacity for stem-cell renewal, consists of a catalytic telomerase reverse transcriptase (TERT) and a template-encoding RNA (TER). TERs from…

Unexpected Gating Behaviour of an Engineered Potassium Channel Kir

In this study, we investigated the dynamics and functional characteristics of the KirBac3.1 S129R, a mutated bacterial potassium channel for which the inner pore-lining helix (TM2) was engineered so that the bundle crossing is trapped in an open…

Structural study of the function of Candida Albicans Pif1

Pif1 helicases, conserved in eukaryotes, are involved in maintaining genome stability in both the nucleus and mitochondria. Here, we report the crystal structure of a truncated Candida Albicans Pif1 (CaP-if1 368À883) in complex with ssDNA and an ATP…

Structural and functional studies of SF1B Pif1 from Thermus oshimai reveal dimerization-induced helicase inhibition

Pif1 is an SF1B helicase that is evolutionarily conserved from bacteria to humans and plays multiple roles in maintaining genome stability in both nucleus and mitochondria. Though highly conserved, Pif1 family harbors a large mechanistic diversity…
