Identification of a Pathogenicity Locus, rpfA, in Erwinia carotovora subsp. carotovora That Encodes a Two-Component Sensor-Regulator Protein

open access: yesMolecular Plant-Microbe Interactions, 1997
A mutant of Erwinia carotovora subsp. carotovora, AH2552, created by a Mud1 insertion was found to be reduced in plant pathogenicity and deficient in extracellular protease and cellulase activity, although it produced normal levels of pectate lyase and ...

Functional Biomaterials Derived from Protein Liquid–Liquid Phase Separation and Liquid‐to‐Solid Transition

open access: yesAdvanced Materials, EarlyView.
Protein can undergo liquid–liquid phase separation and liquid‐to‐solid transition to form liquid condensates and solid aggregates. These phase transitions can be influenced by post‐translational modifications, mutations, and various environmental factors.

Using the structural kinome to systematize kinase drug discovery [PDF]

open access: yesarXiv, 2021
Kinase-targeted drug design is challenging. It requires designing inhibitors that can bind to specific kinases when all kinase catalytic domains share a common folding scaffold that binds ATP. Thus, obtaining the desired selectivity, given the whole human kinome, is a fundamental task during early-stage drug discovery.

Dimer Asymmetry and Light Activation Mechanism in Brucella Blue-Light Sensor Histidine Kinase

open access: yesmBio, 2021
Bacteria employ two-component systems (TCSs) to sense and respond to changes in their surroundings. At the core of the TCS signaling pathway is the multidomain sensor histidine kinase, where the enzymatic activity of its output domain is allosterically ...

Peptide vocabulary analysis reveals ultra-conservation and homonymity in protein sequences [PDF]

open access: yes, 2007
A new algorithm is presented for vocabulary analysis (word detection) in texts of human origin. It performs at 60%–70% overall accuracy and greater than 80% accuracy for longer words, and approximately 85% sensitivity on Alice in Wonderland, a ...

PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

open access: yesAdvanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

Advance in Reversible Covalent Kinase Inhibitors [PDF]

open access: yesarXiv, 2021
Reversible covalent kinase inhibitors (RCKIs) are a class of novel kinase inhibitors attracting increasing attention because they simultaneously show the selectivity of covalent kinase inhibitors, yet avoid permanent protein-modification-induced adverse effects.

Structure of CheA, a Signal-Transducing Histidine Kinase [PDF]

open access: yesCell, 1999
Histidine kinases allow bacteria, plants, and fungi to sense and respond to their environment. The 2.6 A resolution crystal structure of Thermotoga maritima CheA (290-671) histidine kinase reveals a dimer where the functions of dimerization, ATP binding, and regulation are segregated into domains.

The pmrCAB Operon Mediates Polymyxin Resistance In Acinetobacter Baumannii ATCC 17978 And Clinical Isolates Through Phosphoethanolamine Modification Of Lipid A [PDF]

open access: yes, 2011
The emergence of multidrug resistance among Acinetobacter baumannii is leading to an increasing dependence on the use of polymyxins as last-hope antibiotics. Here, we utilized genetic and biochemical methods to define the involvement of the pmrCAB operon

Cardiomyocyte‐Enriched USP20 Ameliorates Pathological Cardiac Hypertrophy by Targeting STAT3 Deubiquitination

open access: yesAdvanced Science, EarlyView.
Cardiomyocyte‐enriched USP20 regulates the K63‐linked ubiquitination of STAT3, and the cardiomyocyte‐specific USP20‐STAT3‐CARM1 axis exerts a protective role in cardiac hypertrophy. Targeting USP20 through cardiac‐specific gene therapy presents a promising strategy for the treatment of cardiac hypertrophy.
