  2. Nucleoside triphosphate - Wikipedia

    en.wikipedia.org/wiki/Nucleoside_triphosphate

    The catalytic site is where the NDP to dNDP reaction takes place, the activity site determines whether or not the enzyme is active, and the specificity site determines which reaction takes place in the catalytic site. The activity site can bind either ATP or dATP. [30] When bound to ATP, RNR is active.

    ntpd-rs is a security-focussed implementation of the NTP protocol, founded by the Internet Security Research Group as part of their Prossimo initiative for the creation of memory safe Internet infrastructure. ntpd-rs is implemented in Rust programming language which offers memory safety guarantees in addition to the Real-time computing ...

  4. Nucleoside-diphosphate kinase - Wikipedia

    en.wikipedia.org/wiki/Nucleoside-diphosphate_kinase

    Nucleoside-diphosphate kinases (NDPKs, also NDP kinase, (poly)nucleotide kinases and nucleoside diphosphokinases) are enzymes that catalyze the exchange of terminal phosphate between different nucleoside diphosphates (NDP) and triphosphates (NTP) in a reversible manner to produce nucleotide triphosphates. Many NDP serve as acceptor while NTP ...
