Highly selective detection of pyrophosphate in the presence of inorganic phosphates, halides, acetate, ATP, other nucleotides in neutral aqueous solutions is achieved by a fluorescent Zn-ensemble based system. The implementation of the first molecule based JK-latch sequential logic function is

A kinetic method has been developed for highly sensitive and selective detection of pyrophosphate anions (PPi) by using a fluorophore labelled single-stranded-DNA-Al(III) complex system. The facile and spectrum-tunable fluorescent sensor enables rapid detection of PPi in urine and cell lysate

Acanthamoeba polyphaga mimivirus tyrosyl-tRNA synthetase (TyrRSapm) was the first reported aminoacyl-tRNA synthetase of viral origin. The previous crystal structure of TyrRSapm showed a non-canonical orientation of the dimer conformation and the CP1 domain, responsible for dimer formation, displays a major

During the process of matrix vesicle (MV)-mediated initiation of mineralisation, chondrocytes and osteoblasts mineralise the extracellular matrix by promoting the seeding of basic calcium phosphate crystals of hydroxyapatite (HA) along the collagen fibrils. This orchestrated process is carefully regulated by

Treatment of HIV-1 with nucleoside reverse transcription inhibitors leads to the emergence of resistance mutations in the reverse transcriptase (RT) gene. Resistance to 3'-azido-3'-deoxythymidine (AZT) and to a lesser extent to 2'-3'-didehydro-2'-3'-dideoxythymidine is mediated by phosphorolytic excision of the chain
