Adrenal Cortical Ribonuclease H (hybrid) (38494).
Ribonuclease Hybrid (RNaseH) from adrenal cortical tissue has been characterized. RNase H specifically degrades the RNA strand of purified RNA:DNA hybrids but is inactive on single- or double-stranded RNA or on DNA. The mode of clevage by RNase H is endonucleolytic, producing oligoribonucleoties with 3'-hydroxyl and 5'- phosphate termini. ACTH administration to guinea pigs results in no detectable change in adrenal cortical RNase H activity at times when changes in DNA synthesis are marked.
