Applicazioni

Ribonuclease T1 (RNase T1) from Aspergillus oryzae is used to digest denatured RNA prior to sequencing and is used for protein folding studies .

Azioni biochim/fisiol

Ribonuclease T1 (RNase T1) from Aspergillus oryzae is an endoribonuclease that hydrolyzes after G residues. Cleavage occurs between the 3′-phosphate group of a guanidine ribonucleotide and 5′-hydroxyl of the adjacent nucleotide. The initial product is a 2′:3′ cyclic phosphate nucleoside that is hydrolyzed to the corresponding 3′-nucleoside phosphate. It differs from Pancreatic RNase in that it attacks the guanine sites specifically to yield 3′-GMP and oligonucleotides with a 3′-GMP terminal group.

Slow protein folding processes during which kinetic folding intermediates occur for an extended time can lead to aggregation and dysfunction in living cells. Therefore, protein folding helpers have evolved, which prevent proteins from aggregation and/or speed up folding processes. In
