title: Amino acid sequence and S-S bonds of Penicillium brevicompactum guanyl-specific ribonuclease.
abstract: The primary structure of Penicillium brevicompactum guanyl-specific RNase was determined. The enzyme consists of 102 amino acid residues, Mr 10801. The 4 cysteine residues of the RNase are linked in pairs by disulfide bonds: Cys2-Cys10, Cys6-Cys101. P. brevicompactum RNase structure is similar to RNase T1; the degree of homology is 66%.
