Respiratory active mitochondrial supercomplexes.
TLDR
It is demonstrated the existence of a functional respirasome and a structural organization model is proposed that accommodates these findings. Expand
NADH Oxidase Activity of Mitochondrial Apoptosis-inducing Factor*
TLDR
Biochemical characterization of AIF's redox activity indicates that AIF has a marked oxidoreductase activity which can be dissociated from its apoptosis-inducing function. Expand
Iron availability affects mcyD expression and microcystin-LR synthesis in Microcystis aeruginosa PCC7806.
TLDR
The results indicate that iron deficiency could be one of the inducing factors of the microcystin synthesis, and for the first time, increased transcription of an essential mcy gene and correlative microcyStin synthesis has been established. Expand
Identification of free-living amoebae and amoeba-associated bacteria from reservoirs and water treatment plants by molecular techniques.
TLDR
The results highlight the importance of amoebae in natural waters as reservoirs of potential pathogens and its possible role in the spread of bacterial genera with interest in public and environmental health. Expand
Fur from Microcystis aeruginosa binds in vitro promoter regions of the microcystin biosynthesis gene cluster.
TLDR
It is shown that Fur from M. aeruginosa binds in vitro promoter regions of several mcy genes, which suggests that Fur might regulate, among other factors, microcystin synthesis. Expand
2‐oxoglutarate enhances NtcA binding activity to promoter regions of the microcystin synthesis gene cluster
TLDR
The results suggest that the 2‐oxoglutarate level, as a signal of the C to N balance of the cells, regulates the microcystin gene cluster. Expand
Identification of a Ferric uptake regulator from Microcystis aeruginosa PCC7806.
TLDR
DNA sequence analysis confirmed the presence of a 183 amino-acid open reading frame that showed high identity with Fur proteins reported for cyanobacteria, and the expression of Fur in Microcystis was induced about twofold in iron-deficient conditions. Expand
Identification of a furA cis antisense RNA in the cyanobacterium Anabaena sp. PCC 7120.
TLDR
Increased expression of FurA in a mutant unable to produce the longer message showed that this transcript acted as an antisense RNA (alpha-furA RNA) interfering with furA transcript translation thus contributing to determine cellular levels of Fur A protein. Expand
Phosphate deficiency (N/P 40:1) induces mcyD transcription and microcystin synthesis in Microcystis aeruginosa PCC7806.
TLDR
It is demonstrated that under phosphate deficiency conditions with a ratio of 40:1 N/P, the growth of M. aeruginosa PCC7806 was not affected when compared to control and phosphate excess samples and the microcystin content in phosphate deficient cells correlates with the trend of mcyD transcription observed. Expand
Characterization of ferredoxin and flavodoxin as markers of iron limitation in marine phytoplankton
TLDR
expression of flavodoxin in T. weissflogii was found to be specific to iron limitation, and was not induced by nitrate, phosphate, silicate, zinc or light deficiency, support its use as an indicator of the presence of iron limitation. Expand
