Improved thermostability of creatinase from Alcaligenes Faecalis through non-biased phylogenetic consensus-guided mutagenesis

open access: yesMicrobial Cell Factories, 2020
Background Enzymatic quantification of creatinine has become an essential method for clinical evaluation of renal function. Although creatinase (CR) is frequently used for this purpose, its poor thermostability severely limits industrial applications ...

Enhancement of protein thermostability by three consecutive mutations using loop-walking method and machine learning

open access: yesScientific Reports, 2021
We developed a method to improve protein thermostability, “loop-walking method”. Three consecutive positions in 12 loops of Burkholderia cepacia lipase were subjected to random mutagenesis to make 12 libraries.

Taming nitroformate through encapsulation with nitrogen-rich hydrogen-bonded organic frameworks

open access: yesNature Communications, 2021
Nitroformate is an attractive oxidant compound in propellants and explosives but its poor thermostability prevents it from application. Here, the authors demonstrate that incorporation of nitroformate in a hydrogen-bonded organic framework increases the ...
