guanylic acid/neoplasms

RNase Po1 is a guanylic acid-specific ribonuclease member of the RNase T1 family from Pleurotus ostreatus. We previously reported that RNase Po1 inhibits the proliferation of human tumor cells, yet RNase T1 and other T1 family RNases are non-toxic. We determined the three-dimensional X-ray structure

RNase He1 is a guanylic acid-specific ribonuclease of the RNase T1 family from Hericium erinaceus (Japanese name: Yamabushitake). Its RNA degrading activity is strongly inhibited by Zn²⁺, similar to other T1 family RNases. However, RNase He1 shows little inhibition of human tumor cell

Here, we determined the sequence of a cDNA encoding a guanylic acid-specific ribonuclease (RNase He1) from Hericium erinaceus that exhibits high sequence identity (59%) with RNase Po1, an enzyme with anti-cancer activity and which is found in Pleurotus ostreatus. RNase He1 and RNase Po1 have similar
