Hypoxanthine-Guanine Phosphoribosyltransferase/adenylate Kinase From Zobellia galactanivorans: A Bifunctional Catalyst for the Synthesis of Nucleoside-5′-Mono-, Di- and Triphosphates [PDF]
In our search for novel biocatalysts for the synthesis of nucleic acid derivatives, we found a good candidate in a putative dual-domain hypoxanthine-guanine phosphoribosyltransferase (HGPRT)/adenylate kinase (AMPK) from Zobellia galactanivorans (ZgHGPRT ...

Investigation of the functional hot-spot residues of an enzyme by real-time monitoring of the enzymatic reaction using NMR and computational approaches [PDF]
Favipiravir is an anti-influenza prodrug that is metabolized to its phosphoribosylated form, favipiravir-ribofuranosyl-5′-monophosphate (favipiravir-RMP), by human endogenous enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRT).

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway. [PDF]
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence. [PDF]
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.

Biosynthesis and Genetic Tuning of Guanine Crystals via Metabolic Engineering of Yeast. [PDF]
We demonstrate how yeast cells can be harnessed as cellular factories for the synthesis of optically functional guanine crystals, where genetic editing is used to tune crystal size, order and optical properties. This demonstrates a powerful new biosynthetic approach for the development of sustainable and biocompatible optical pigments, which utilizes ...

Adeno‐associated virus serotype 2 capsid variants for improved liver‐directed gene therapy
Abstract Background and Aims Current liver‐directed gene therapies look for adeno‐associated virus (AAV) vectors with improved efficacy. With this background, capsid engineering is explored. Whereas shuffled capsid library screenings have resulted in potent liver targeting variants with one first vector in human clinical trials, modifying natural ...

Case of Self-Mutilation –Lesch-Nyhan Syndrome
Lesch-Nyhan syndrome involves a congenital error of purine metabolism, due to the absence (or very low levels) of hypoxanthine-guanine phosphoribosyltransferase (HPRT) enzyme. The classic clinical phenotype of LNS was first described by Michael Lesch and
