NTRC links built-in thioredoxin to light and sucrose in regulating starch synthesis in chloroplasts and amyloplasts
(2009)
Plants have an unusual plastid-localized NADP-thioredoxin reductase C (NTRC) containing both an NADP-thioredoxin reductase (NTR) and a thioredoxin (Trx) domain in a single polypeptide. Although NTRC is known to supply ...

Cytochrome c lysine acetylation regulates cellular respiration and cell death in ischemic skeletal muscle
(Springer Nature, 2023)
Skeletal muscle is more resilient to ischemia-reperfusion injury than other organs. Tissue specific post-translational modifications of cytochrome c (Cytc) are involved in ischemia-reperfusion injury by regulating mitochondrial ...

Site-directed Mutagenesis of Cytochromec 6 from Synechocystissp. PCC 6803
(Elsevier, 1999)
This paper reports the first site-directed mutagenesis analysis of any cytochrome c 6, a heme protein that performs the same function as the copper-protein plastocyanin in the electron transport chain of photosynthetic ...

Functional dependence between septal protein SepJ from Anabaena sp. Strain PCC 7120 and an amino acid ABC-type uptake transporter
(American Society for Microbiology, 2015)
In the diazotrophic filaments of heterocyst-forming cyanobacteria, two different cell types, the CO2-fixing vegetative cells and the N2-fixing heterocysts, exchange nutrients, including some amino acids. In the model ...

Microglia in Alzheimer’s Disease: Activated, Dysfunctional or Degenerative
(Frontiers Media, 2018)
Microglial activation has been considered a crucial player in the pathological process of multiple human neurodegenerative diseases. In some of these pathologies, such as Amyotrophic Lateral Sclerosis or Multiple Sclerosis, ...

Nitrogen-regulated antisense transcription in the adaptation to nitrogen deficiency in Nostoc sp. PCC 7120
(Oxford University Press, 2023-06-02)
Transcriptomic analyses using high-throughput methods have revealed abundant antisense transcription in bacteria. Antisense transcription is often due to the overlap of mRNAs with long 5′ or 3′ regions that extend beyond ...

Photorespiration: regulation and new insights on the potential role of persulfidation
(Oxford University Press, 2023-07-24)
Photorespiration has been considered a 'futile' cycle in C3 plants, necessary to detoxify and recycle the metabolites generated by the oxygenating activity of Rubisco. However, several reports indicate that this metabolic ...

Programmed cell death (PCD): an essential process of cereal seed development and germination
(Frontiers media, 2014)
The life cycle of cereal seeds can be divided into two phases, development and germination, separated by a quiescent period. Seed development and germination require the growth and differentiation of new tissues, but ...

Nicotinamide N-methyltransferase (NNMT) regulates the glucocorticoid signaling pathway during the early phase of adipogenesis
(Springer Nature, 2023-05-22)
Obesity is associated with adipose tissue dysfunction through the differentiation and expansion of pre-adipocytes to adipocytes (hyperplasia) and/or increases in size of pre-existing adipocytes (hypertrophy). A cascade of ...

Characterization of the response to zinc deficiency in the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2012)
Zur regulators control zinc homeostasis by repressing target genes under zinc-sufficient conditions in a wide variety of bacteria. This paper describes how part of a survey of duplicated genes led to the identification of ...
