Ferredoxins: master regulators in mitochondrial redox homeostasis and programmed cell death

Redox Biology
Ferredoxins (FDXs) are evolutionarily conserved iron-sulfur (Fe–S) proteins that serve as master regulators of mitochondrial redox homeostasis, governing critical processes including electron transfer, energy metabolism, Fe–S cluster biogenesis, and ...

Family-specific scaling laws in bacterial genomes [PDF]

, 2017
Among several quantitative invariants found in evolutionary genomics, one of the most striking is the scaling of the overall abundance of proteins, or protein domains, sharing a specific functional annotation across genomes of given size.

Automatically Defining Protein Words for Diverse Functional Predictions Based on Attention Analysis of a Protein Language Model

Advanced Science, EarlyView.
Understanding protein sequence–function relationships remains challenging due to poorly defined motifs and limited residue‐level annotations. An annotation‐agnostic framework is introduced that segments protein sequences into “protein words” using attention patterns from protein language models.

Biokinetics Of microbial consortia using biogenic sulfur as a novel electron donor for sustainable denitrification [PDF]

, 2018
In this study, the biokinetics of autotrophic denitrification with biogenic S0 (ADBIOS) for the treatment of nitrogen pollution in wastewaters were investigated. The used biogenic S0, a by-product of gas desulfurization, was an elemental microcrystalline
