A Bifunctional Protease Cleaves the Leader Peptide in the Biosynthesis of Class I Microviridins. [PDF]

Chembiochem
Biochemical characterization of the peptidase candidate NosP reveals bifunctional endo‐ and aminopeptidase activity in the leader peptide removal of class I microviridins from Nostoc punctiforme. The discovery of the first leader‐processing peptidase from microviridin biosynthesis may pave the way for the efficient production and bioengineering of ...

Anabaenopeptins from Nostoc edaphicum CCNP1411

International Journal of Environmental Research and Public Health, 2022
Cyanobacteria of the Nostoc genus belong to the most prolific sources of bioactive metabolites. In our previous study on Nostoc edaphicum strain CCNP1411, the occurrence of cyanopeptolins and nostocyclopeptides was documented. In the current work, the production of anabaenopeptins (APs) by the strain was studied using genetic and chemical methods ...

Cytochrome c 6-like protein as a putative donor of electrons to photosystem I in the cyanobacterium Nostoc sp. PCC 7119 [PDF]

, 2011
Most organisms performing oxygenic photosynthesis contain either cytochrome c 6 or plastocyanin, or both, to transfer electrons from cytochrome b 6-f to photosystem I. Even though plastocyanin has superseded cytochrome c 6 along evolution, plants contain

NsrR1, a Nitrogen stress-repressed sRNA, contributes to the regulation of nblA in Nostoc sp. PCC 7120 [PDF]

, 2018
Small regulatory RNAs (sRNAs) are currently considered as major post-transcriptional regulators of gene expression in bacteria. The interplay between sRNAs and transcription factors leads to complex regulatory networks in which both transcription factors

New Nostocyclophanes from Nostoc linckia

Marine Drugs, 2023
Six new nostocyclophanes and four known compounds have been isolated from Nostoc linckia (Nostocaceae) cyanobacterial strain UTEX B1932. The new compounds, nostocyclophanes E–J (1–6), were characterized by NMR and MS techniques. The known compounds were nostocyclophanes B–D, previously isolated from this strain, and dedichloronostocyclophane D ...

Species in section Peltidea ( aphthosa group) of the genus Peltigera remain cryptic after molecular phylogenetic revision

Plant and Fungal Systematics, 2018
Closely related lichen-forming fungal species circumscribed using phenotypic traits (morphospecies) do not always align well with phylogenetic inferences based on molecular data.

Exploration of the aptitude to alleviate oxidative impairment and curb colorectal cancer manifestation by Nostoc calcicola in HT-29 adenocarcinoma cells

Future Journal of Pharmaceutical Sciences, 2023
Background Marine cyanobacteria have been known to contain several unique bioactive compounds which have different therapeutic potentials. The current research focuses to identify the efficacy of Nostoc calcicola to counteract the harmful effects of free

Effect of crowding on the electron transfer process from plastocyanin and cytochrome c6 to photosystem I: a comparative study from cyanobacteria to green algae [PDF]

, 2011
Plastocyanin and cytochrome c 6, the alternate donor proteins to photosystem I, can be acidic, neutral or basic; the role of electrostatics in their interaction with photosystem I vary accordingly for cyanobacteria, algae and plants.

Cyt c6-3: A new isoform of photosynthetic Cyt c6 exclusive to heterocyst-forming cyanobacteria [PDF]

, 2017
All known cyanobacteria contain Cyt c6, a small soluble electron carrier protein whose main function is to transfer electrons from the Cyt b6 f complex to PSI, although it is also involved in respiration.

Impact of Environmentally Relevant Concentrations of Glyphosate and 2,4-D Commercial Formulations on Nostoc sp. N1 and Oryza sativa L. Rice Seedlings

Frontiers in Sustainable Food Systems, 2021
Wide applications of glyphosate and 2,4-dichlorophenoxyacetic acid (2,4-D) in rice paddy fields could lead to their residues in environment, posing adverse effects on rice growth and primary producers in the rice ecosystem.
