The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity
FEBS Letters, EarlyView.The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

On the reducibility of “16 + 16” supergravity
Physics Letters B, 1986 Abstract It is shown, in the framework of N = 1, d = 4 superconformal tensor calculus, that the recently proposed supergravity theory based on a 16 + 16 multiplet is reducible and equivalent to either a real linear multiplet coupled to old minimal supergravity or to a chiral multiplet coupled to new minimal supergravity.

Accuracy of taxonomy prediction for 16S rRNA and fungal ITS sequences
PeerJ, 2018 Prediction of taxonomy for marker gene sequences such as 16S ribosomal RNA (rRNA) is a fundamental task in microbiology. Most experimentally observed sequences are diverged from reference sequences of authoritatively named organisms, creating a challenge

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Do calcifying nanoparticles really contain 16S rDNA?
International Journal of Nanomedicine, 2012 Farooq A ShiekhAix-Marseille Université, URMITE, UMR, CNRS 7278, IRD 198, Marseille, FranceWith great interest, I read a recent article published in the International Journal of Nanomedicine by Guo et al.1 This study involved an analysis of ...

International Journal of Medical MicrobiologyBackground: Currently, diagnosis of bacterial infections is based on culture, possibly followed by the amplification and sequencing (Sanger method) of the 16S rDNA - encoding gene when cultures are negative. Clinical metagenomics (CMg), i.e.

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
