DNA region responsible for transcriptional regulation of the Escherichia coli penicillin amidase (pac) gene by CRP and PAA
(Elsevier, Amsterdam, 1999)
Transcriptional regulation of Escherichia coli ATCC11105 penicillin amidase gene (pac) by cAMP receptor protein (CRP) and phenylacetic acid (PAA) was studied by using operon fusions with divergent reporter gene (lacZ, and ...
Den 1, den 2 and den 3, ATP-inhibited deoxyribonucleases from Dropsophila embryonic nuclei
(Springer, Dordrecht, 1998)
Three Drosophila embryonic deoxyribonucleases, designated den1, den2 and den3, are identified in nuclear extracts separated by glycerol density gradient centrifugation. Den1, removes short products from the 5'-ends of ...
