Identification of an acetyl esterase in the supernatant of the environmental strain Bacillus sp. HR21-6
(Elsevier, 2022)
Bacillus sp. HR21-6 is capable of the chemo- and regioselective synthesis of lipophilic partially acetylated phenolic compounds derived from olive polyphenols, which are powerful antioxidants important in the formulation ...

The chromatin network helps prevent cancer-associated mutagenesis at transcription-replication conflicts
(Nature Research, 2023)
Genome instability is a feature of cancer cells, transcription being an important source of DNA damage. This is in large part associated with R-loops, which hamper replication, especially at head-on transcription-replication ...

Saccharomyces cerevisiae Aqr1 is an internal-membrane transporter involved in excretion of amino acids
(American Society for Microbiology, 2004)
Excretion of amino acids by yeast cells was reported long ago but has not been characterized in molecular terms. It is typically favored by overproduction of the amino acid and/or impairment of its uptake. Here we describe ...

PAI1 is a Marker of Bad Prognosis in Rectal Cancer but Predicts a Better Response to Treatment with PIM Inhibitor AZD1208
(MDPI, 2020)
Colorectal cancer (CRC) is the third most common cancer worldwide. The standard treatment in locally advanced rectal cancer is preoperative radiation alone or in combination with chemotherapy, followed by adjuvant chemotherapy. ...

Ribosomal protein eL39 is important for maturation of the nascent polypeptide exit tunnel and proper protein folding during translation
(Oxford University Press, 2022)
During translation, nascent polypeptide chains travel from the peptidyl transferase center through the nascent polypeptide exit tunnel (NPET) to emerge from 60S subunits. The NPET includes portions of five of the six ...

Coupling Between Cell Cycle Progression and the Nuclear RNA Polymerases System
(Frontiers Media S.A., 2021)
Eukaryotic life is possible due to the multitude of complex and precise phenomena that take place in the cell. Essential processes like gene transcription, mRNA translation, cell growth, and proliferation, or membrane ...

The Terminal Extensions of Dbp7 Influence Growth and 60S Ribosomal Subunit Biogenesis in Saccharomyces cerevisiae
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Ribosome synthesis is a complex process that involves a large set of protein trans-acting factors, among them DEx(D/H)-box helicases. These are enzymes that carry out remodelling activities onto RNAs by hydrolysing ATP. ...

Interactions between Bacteria and Bile Salts in the Gastrointestinal and Hepatobiliary Tracts
(Frontiers Media, 2017)
Bile salts and bacteria have intricate relationships. The composition of the intestinal pool of bile salts is shaped by bacterial metabolism. In turn, bile salts play a role in intestinal homeostasis by controlling the ...

The role of chromatin at transcription-replication conflicts as a genome safeguard
(Portland Press, 2021)
DNA replication ensures the correct copying of the genome and the faithful transfer of the genetic information to the offspring. However, obstacles to replication fork (RF) progression cause RF stalling and compromise ...
