Critical behavior of megabase-size DNA toward the transition into a compact state.
We studied the changes in the higher-order structure of a megabase-size DNA (S120-1 DNA) under different spermidine (SPD) concentrations through single-molecule observations using fluorescenceExpand

Naturally occurring branched-chain polyamines induce a crosslinked meshwork structure in a giant DNA.
We studied the effect of branched-chain polyamines on the folding transition of genome-sized DNA molecules in aqueous solution by the use of single-molecule observation with fluorescence microcopy.Expand

Mutation design of a thermophilic Rubisco based on three‐dimensional structure enhances its activity at ambient temperature
Ribulose‐1,5‐bisphosphate carboxylase/oxygenase (Rubisco) plays a central role in carbon dioxide fixation on our planet. Rubisco from a hyperthermophilic archaeon Thermococcus kodakarensisExpand

Identification of Branched-Chain Polyamines in Hyperthermophiles.
Thermophiles are organisms that grow optimally at temperatures higher than 55 °C. They contain two types of unusual longer/branched-chain polyamines in addition to common polyamines such asExpand
