A Single Complementary-Sense Transcript of a Geminiviral DNA β Satellite Is Determinant of Pathogenicity

Molecular Plant-Microbe Interactions, 2005
Small circular single-stranded DNA satellites, termed DNAβ, have recently been found associated with some geminivirus infections. The DNA β associated with Cotton leaf curl virus is responsible for symptom expression of a devastating disease in Pakistan.

Primary structure of prostaglandin G/H synthase from sheep vesicular gland determined from the complementary DNA sequence.

Proceedings of the National Academy of Sciences of the United States of America, 1988
Prostaglandin G/H synthase (8,11,14-icosatrienoate, hydrogen-donor:oxygen oxidoreductase, EC 1.14.99.1) catalyzes the first step in the formation of prostaglandins and thromboxanes, the conversion of arachidonic acid to prostaglandin endoperoxides G and ...
