Structure of the Complex between Plastocyanin and Cytochrome f from the Cyanobacterium Nostoc sp. PCC 7119 as Determined by Paramagnetic NMR
(Elsevier, 2005)
The complex between cytochrome f and plastocyanin from the cyanobacterium Nostoc has been characterized by NMR spectroscopy. The binding constant is 16 mm–1, and the lifetime of the complex is much less than 10 ms. ...

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 ...

Stress response requires an efficient connection between glycogen and central carbon metabolism by phosphoglucomutases in cyanobacteria
(Oxford University Press, 2023-03-13)
Glycogen and starch are the main storage polysaccharides, acting as a source of carbon and energy when necessary. Interconversion of glucose-1-phosphate and glucose-6-phosphate by phosphoglucomutases connects the metabolism ...

Glutamine, MTOR and autophagy: a multiconnection relationship
(Taylor & Francis, 2022)
Cancer cells metabolize glutamine mostly through glutaminolysis, a metabolic pathway that activates MTORC1. The AMPK-MTORC1 signaling axis is a key regulator of cell growth and proliferation. Our recent investigation ...

Specific role of the cyanobacterial pipX factor in the heterocysts of Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2011)
The PipX factor is a regulatory protein that seems to occur only in cyanobacteria. In the filamentous, heterocyst-forming Anabaena sp. strain PCC 7120, open reading frame (ORF) asr0485, identified as the pipX gene, is ...

Altered nuclear tRNA metabolism in La-deleted Schizosaccharomyces pombe is accompanied by a nutritional stress response involving Atf1p and Pcr1p that is suppressible by Xpo-t/Los1p
(American Society for Cell Biology, 2012)
Deletion of the sla1+ gene, which encodes a homologue of the human RNA-binding protein La in Schizosaccharomyces pombe, causes irregularities in tRNA processing, with altered distribution of pre-tRNA intermediates. We show, ...
