Journal ArticleDOI
A Role for the ESCRT System in Cell Division in Archaea
TL;DR: It is found that Sulfolobus ESCRT-III and Vps4 homologs underwent regulation of their expression during the cell cycle, and these proteins specifically localized to the mid-cell during cell division.
Journal ArticleDOI
Molecular and Structural Basis of ESCRT-III Recruitment to Membranes during Archaeal Cell Division
Rachel Y. Samson,Takayuki Obita,Ben Hodgson,Michael K. Shaw,Parkson Lee-Gau Chong,Roger L. Williams,Stephen D. Bell +6 more
TL;DR: A protein, CdvA, is identified that is responsible for recruiting Sulfolobus ESCRT-III to membranes and gives insight into the evolution of the more complex and modular eukaryotic ESCRT complex.
Journal ArticleDOI
Electron cryotomography of ESCRT assemblies and dividing Sulfolobus cells suggests that spiraling filaments are involved in membrane scission
Megan J. Dobro,Rachel Y. Samson,Zhiheng Yu,John McCullough,H. Jane Ding,Parkson Lee-Gau Chong,Stephen D. Bell,Grant J. Jensen +7 more
TL;DR: ESCRT filaments wrap helically around liposomes and assemble into various helical structures in vitro, suggesting that spiraling filaments are involved in membrane scission.
Journal ArticleDOI
Specificity and Function of Archaeal DNA Replication Initiator Proteins
Rachel Y. Samson,Rachel Y. Samson,Yanqun Xu,Yanqun Xu,Catarina Gadelha,Todd A. Stone,Jamal N. Faqiri,Dongfang Li,Nan Qin,Fei Pu,Yun Xiang Liang,Qunxin She,Qunxin She,Stephen D. Bell,Stephen D. Bell +14 more
TL;DR: The nonessential nature of the orc1-1 gene is exploited to investigate the role of ATP binding and hydrolysis in initiator function in vivo and in vitro and it is found that the ATP-bound form of Orc 1-1 is proficient for replication and implicates hydrolytic of ATP in downregulation of origin activity.
Journal ArticleDOI
Ancient ESCRTs and the evolution of binary fission
Rachel Y. Samson,Stephen D. Bell +1 more
TL;DR: Two distinct machineries to drive binary fission have evolved in prokaryotes - onedependent on tubulin-like proteins and one dependent on the ESCRT system.
