| Abstract: | The primary structure of ribonuclease F1, the guanine specific ribonuclease from Fusarium moniliforme, has been determined. Ribonuclease F1 consists of 106 amino acid residues and has a molecular weight of 10,980. It has a pyroglutamyl residue at the N-terminus. Comparison of the primary structures of four fungal ribonucleases so far sequenced shows that the amino acid sequences around the assumed active site residues are indeed well conserved. However, structurally important half cystine residues are arranged variously. |
