Increased sensitivity to protein synthesis inhibitors in cells lacking tmRNA
(Cold Spring Harbor Laboratory Press, 2001)
tmRNA (also known as SsrA or 10Sa RNA) is involved in a trans-translation reaction that contributes to the recycling of stalled ribosomes at the 3′ end of an mRNA lacking a stop codon or at an internal mRNA cluster of rare ...

A Single Arginyl Residue in Plastocyanin and in Cytochrome c6 from the Cyanobacterium Anabaenasp. PCC 7119 Is Required for Efficient Reduction of Photosystem I
(Elsevier, 2001)
Positively charged plastocyanin from Anabaena sp. PCC 7119 was investigated by site-directed mutagenesis. The reactivity of its mutants toward photosystem I was analyzed by laser flash spectroscopy. Replacement of arginine ...

Role of two NtcA-binding sites in the complex ntcA gene promoter of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2008)
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that fixes N2 in specialized cells called heterocysts, which differentiate from vegetative cells in a process that requires the nitrogen control transcription ...

Phosphorylation-mediated unfolding of a KH domain regulates KSRP localization via 14-3-3 binding
(Nature Research, 2009)
The AU-rich element (ARE)-mediated mRNA-degradation activity of the RNA binding K-homology splicing regulator protein (KSRP) is regulated by phosphorylation of a serine within its N-terminal KH domain (KH1). In the cell, ...

Detergent effect on cytochrome b559 electron paramagnetic resonance signals in the photosystem II reaction centre
(Wiley, 2003)
Detergent effect on Cytochrome b559 from spinach photosystem II was studied by electron paramagnetic resonance (EPR) spectroscopy in D1-D2-Cyt b559 complex preparations. Various n-dodecyl-β-D-maltoside ...
