Journal ArticleDOI
PprA: a novel protein from Deinococcus radiodurans that stimulates DNA ligation
TL;DR: Investigating the DNA damage repair‐deficient mutant, KH311, showed that a unique radiation‐inducible gene (designated pprA) responsible for loss of radiation resistance was identified, suggesting that D. radiodurans has a radiation‐induced non‐homologous end‐joining repair mechanism in which PprA plays a critical role.
Journal ArticleDOI
Analysis of mutations induced by carbon ions in Arabidopsis thaliana.
Naoya Shikazono,Chihiro Suzuki,Satoshi Kitamura,Hiroshi Watanabe,Shigemitsu Tano,Atsushi Tanaka +5 more
TL;DR: The results indicated that carbon-ion-induced mutations are most likely nulls and that the induced rearrangements may arise through a unique mechanism, indicating that accelerated ions are a useful mutagen for both forward and reverse genetics for plants.
Journal ArticleDOI
A blue protein as an inactivating factor for nitrite reductase from Alcaligenes faecalis strain S-6.
TL;DR: A suicide inactivation mechanism of the enzyme due to this H2O2 production is proposed.
Journal ArticleDOI
Purification and properties of a copper-containing nitrite reductase from a denitrifying bacterium, Alcaligenes faecalis strain S-6.
TL;DR: A copper-containing nitrite reductase was purified and crystallized from a potent denitrifying bacterium, Alcaligenes faecalis strain S-6, and nitric oxide was identified as a main reduction product from nitrite in the enzyme-catalyzed reaction.
Journal ArticleDOI
Mutation rate and novel tt mutants of Arabidopsis thaliana induced by carbon ions.
Naoya Shikazono,Yukihiko Yokota,Satoshi Kitamura,Chihiro Suzuki,Hiroshi Watanabe,Shigemitsu Tano,Atsushi Tanaka +6 more
TL;DR: The isolation of novel mutants and the high mutation rate suggest that ion particles can be used as a valuable mutagen for plant genetics.
