Crystal structures of PCNA1 and PCNA2 from Aeropyrum pernix: implications for a distorted heterotrimeric sliding clamp
{{output}}
Aeropyrum pernix is a hyperthermophilic archaeon that possesses three proliferating cell nuclear antigen (PCNA) isoforms (ApePCNA1, ApePCNA2 and ApePCNA3) that form a heterotrimeric sliding clamp. To gain more detailed structural insights into this heterotrime... ...
