那些生物体内的酶为RNA

RNA本质的酶实际上催化范围和功能都是非常小的,目前发现的R酶都只能催化自身或者别的RNA水解,它们的催化特异性是由碱基互补配对来提供的.典型的R酶就是真核生物mRNA成熟过程中mRNA内含子的自剪切.目前发现的R酶我给你列举下,你有兴趣可以自己去查下.
Peptidyl transferase 23S rRNA
RNase P
Group I and Group II introns
GIR1 branching ribozyme[9]
Leadzyme - Although initially created in vitro,natural examples have been found
Hairpin ribozyme
Hammerhead ribozyme
HDV ribozyme
Mammalian CPEB3 ribozyme
VS ribozyme
glmS ribozyme
CoTC ribozyme
