Restriction & Modification Enzymes
Restriction and modification enzymes serve as nature’s genetic gatekeepers. These specialized proteins function together as a defence mechanism in bacteria and protect them from invading foreign DNA, such as that of bacteriophages. Restriction enzymes, also known as restriction endonucleases, recognize specific sequences within the DNA and cleave it at

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Accelerated search kinetics mediated by redox reactions of DNA repair enzymes [PDF]
A Charge Transport (CT) mechanism has been proposed in several papers (e.g., Yavin, et al. PNAS, v102 3546 (2005)) to explain the localization of Base Excision Repair (BER) enzymes to lesions on DNA. The CT mechanism relies on redox reactions of iron-sulfur cofactors that modify the enzyme's binding affinity.

Restriction enzyme digestion of hemimethylated DNA [PDF]
Hemimethylated duplex DNA of the bacteriophage phi X 174 was synthesized using primed repair synthesis is in vitro with E. coli DNA polymerase I followed by ligation to produce the covalently closed circular duplex (RFI). Single-stranded phi X DNA was used as a template, a synthetic oligonucleotide as primer and 5-methyldeoxycytidine-5'-triphosphate ...

Making tau amyloid models in vitro: a crucial and underestimated challenge
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

PCR-RFLP Using BseDI Enzyme for Pork Authentication in Sausage and Nugget Products [PDF]
A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using BseDI restriction enzyme had been applied for identifying the presence of pork in processed meat (beef sausage and chicken nugget) including before and after frying ...

Restriction enzymes use a 24 dimensional coding space to recognize 6 base long DNA sequences [PDF]
Restriction enzymes recognize and bind to specific sequences on invading bacteriophage DNA. Like a key in a lock, these proteins require many contacts to specify the correct DNA sequence. Using information theory we develop an equation that defines the number of independent contacts, which is the dimensionality of the binding. We show that EcoRI, which
