The dynamin A ring complex: molecular organisation and nucleotide-dependent conformational changes (2002)

Klockow,Boris, Tichelaar,Willem, Madden,Dean R., Niemann,Hartmut H., Akiba,Toshihiko, Hirose,Keiko, ...

Here we show that Dictyostelium discoideum dynamin A is a fast GTPase, binds to negatively charged lipids, and self-assembles into rings and helices in a nucleotide-dependent manner, similar to human...

Structure of RadB recombinase from a hyperthermophilic archaeon, Thermococcus kodakaraensis KOD1: an implication for the formation of a near-7-fold helical assembly

Akiba, Toshihiko, Ishii, Noriyuki, Rashid, Naeem, Morikawa, Masaaki, Imanaka, Tadayuki, Harata, Kazuaki

The X-ray crystal structure of RadB from Thermococcus kodakaraensis KOD1, an archaeal homologue of the RecA/Rad51 family proteins, have been determined in two crystal forms. The structure represents...

Structural basis for recognition of the matrix attachment region of DNA by transcription factor SATB1

Yamasaki, Kazuhiko, Akiba, Toshihiko, Yamasaki, Tomoko, Harata, Kazuaki

Special AT-rich sequence binding protein 1 (SATB1) regulates gene expression essential in immune T-cell maturation and switching of fetal globin species, by binding to matrix attachment regions...

Role of Trp140 at subsite −6 on the maltohexaose production of maltohexaose-producing amylase from alkalophilic Bacillus sp.707

Kanai, Ryuta, Haga, Keiko, Akiba, Toshihiko, Yamane, Kunio, Harata, Kazuaki

Maltohexaose-producing amylase (G6-amylase) from alkalophilic Bacillus sp.707 predominantly produces maltohexaose (G6) in the yield of >30% of the total products from short-chain amylose (DP = 17)....

Role of Phe283 in enzymatic reaction of cyclodextrin glycosyltransferase from alkalophilic Bacillus sp.1011: Substrate binding and arrangement of the catalytic site

Kanai, Ryuta, Haga, Keiko, Akiba, Toshihiko, Yamane, Kunio, Harata, Kazuaki

Cyclodextrin glycosyltransferase (CGTase) belonging to the α-amylase family mainly catalyzes transglycosylation and produces cyclodextrins from starch and related α-1,4-glucans. The catalytic site...
