REACTION DIAGRAM
5'-mononucleotide + tRNA
-
ribonuclease D is not essential for the normal growth of Escherichia coli or bacteriophage T4 or for the biosynthesis of a T4 suppressor tRNA
-
-
?
tRNA containing extra residues at the 3'-terminus
5'-mononucleotide + tRNA
-
the enzyme can act at the 3'-terminus of tRNA in vivo. RNase D participates in tRNA metabolism
-
-
?
?
-
-
enzyme is involved in structured RNA processing
-
-
?
additional information
?
-
-
the enzyme may represent an intracellular scavenging mechanism for denatured tRNAs and other inactive RNA molecules
