Selection of antibody-binding covalent aptamers
Aptamers are oligonucleotides with antibody-like binding function, selected from large combinatorial libraries. In this study, we modified a DNA aptamer library with N-hydroxysuccinimide esters, enabling covalent conjugation with cognate proteins.

Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Postsynthetic Covalent Modification of a Neutral Metal−Organic Framework
The covalent modification of the metal−organic framework IRMOF-3 has been achieved using acetic anhydride. Mass spectrometry and 1H NMR evidence shows that the free amine groups in IRMOF-3 are converted to amides in high yields. Control experiments and X-

Covalent Modification of Bacteriophage T4 DNA Inhibits CRISPR-Cas9
The genomic DNAs of tailed bacteriophages are commonly modified by the attachment of chemical groups. Some forms of DNA modification are known to protect phage DNA from cleavage by restriction enzymes, but others are of unknown function.

Mass spectrometry based identification of AMP‐O‐Tris generated by Thermococcus onnurineus Cas10
Isolated Thermococcus onnurineus Cas10 generates the noncanonical ATP‐derived product AMP‐O‐Tris while in Tris‐containing buffer as identified via mass spectrometry, revealing relaxed nucleophile selectivity under isolated conditions. These findings suggest that multiprotein Csm complex assembly restricts Cas10 reactivity toward canonical cyclic ...

Deciphering the phosphorylation of chitosan through complementary 1H and 31P{1H} DOSY NMR
Chemical modification of chitosan through phosphorylation has gained significant attention for expanding its applications. However, confirming whether phosphorylating agents form covalent bonds with the chitosan backbone or remain as non-covalently ...

Selective Covalent Targeting of SARS-CoV-2 Main Protease by Enantiopure Chlorofluoroacetamide
The pandemic of COVID-2019 has urged the development of antiviral agents against its causative pathogen SARS-CoV-2. The main protease (Mpro), a cysteine protease essential for viral replication, is a promising protein target.

Rho GTPase regulation by miRNAs and covalent modifications [PDF]
To date, most studies of Rho GTPase regulation have focused on the classic GTPase cycle - GTP binding and hydrolysis - controlled by guanine nucleotide exchange factors (GEFs), GTPase-activating proteins (GAPs) and GDP-dissociation inhibitors (GDIs).
