Protein: Ribonuclease bn Uniprot ID: P0A8V0 GO: zinc ion-binding Evidence: IDA
Fig. 1a – In solution, zinc ions bind to two locations of the two subunits, in the active site of each
Fig. 1b – This allows for the binding of two amino acids (yellow) and zinc ligands (blue), preparing the protein for cleavage of pre-tRNA.
