beta-Galactosidase chimeras: primary structure of a lac repressor-beta-galactosidase protein. [PDF]

Proceedings of the National Academy of Sciences, 1978
A protein possessing both lac repressor and beta-galactosidase activities in a single polypeptide of about 155,000 daltons was purified from a deletion mutant of Escherichia coli in which the lacI and Z genes are fused. A 77-residue cyanogen bromide peptide containing the fusion joint was isolated.

The CXCL5/CXCR2 Axis Attenuates Ferroptosis in Intrahepatic Cholangiocarcinoma Through the Positive Feedback Loop Between PTGS2 Transcriptional Activation and Neutrophil Recruitment

Advanced Science, EarlyView.
The CXCL5/CXCR2 axis directly inhibits ferroptosis in ICC cells by activating the NF‐κB/PTGS2 pathway. Meanwhile, the CXCL5/CXCR2 axis recruits N2 TANs, and the activated PTGS2 promotes the secretion of TNF‐α from the recruited N2 TANs via the CCL2/CCL7/CCR2 pathway, thereby activating the NF‐κB/PTGS2 axis and forming a positive feedback loop, which ...

Structure of pyridindolol, inhibitor of .BETA.-galactosidase.

The Journal of Antibiotics, 1975
Pyridindolol is a product of a streptomyces and exhibits inhibitory activity against bovine liver beta-galactosidase. The structure of pyridindilol, 1-[1(R), 2-dihydroxyethyl]-3-hydroxymethyl-9H-pyrido[3,4-b] indole, has been established by spectroscopic analyses and an X-ray structure determination.

A Microenvironment‐Adaptive Scaffold Rejuvenates Peripheral Nerve Regeneration During Aging Via Dual Modulation of Ferroptotic Stimuli in Schwann Cells

Advanced Science, EarlyView.
(i) Aging impairs peripheral nerve regeneration via its dual ferroptosis‐mediated pathologies in senescent schwann cells. (ii) The composite nerve conduit is a symbiosis niche integrating microenvironment‐responsive nanoparticles (Ga‐PTAs) and maxillofacial‐derived mesenchymal stem cells (Mmscs).

Impaired Chaperone‐Mediated Autophagy Accelerates Intervertebral Disc Degeneration by Inducing MIDN Accumulation to Target TSC2 for Proteasomal Degradation

Advanced Science, EarlyView.
This graphical abstract illustrates how chaperone‐mediated autophagy (CMA) regulates intervertebral disc degeneration (IDD). Under normal homeostasis (B), CMA degrades cytoplasmic Midnolin (MIDN) to maintain proteostasis. Under inflammatory stress (A), impaired CMA leads to cytoplasmic MIDN accumulation.

Beta galactosidases in Arabidopsis and tomato–a mini review [PDF]

Biochemical Society Transactions, 2016
Beta galactosidases (BGALs) are glycosyl hydrolases that remove terminal β-D-galactosyl residues from β-D-galactosides. There are 17 predicted BGAL genes in the genomes of both Arabidopsis (BGAL1–17) and tomato (TBG1–17). All tested BGALs have BGAL activity but their distinct expression profiles and ancient phylogenetic separation indicates that these ...
