We have determined that 3 mol of ATP or other adenine nucleotide can bind to Escherichia coli transcription termination protein rho, in the presence or absence of the RNA cofactor that is required for activation of rho's ATPase activity. Isotope

Human Cdc25C is a protein phosphatase that dephosphorylates and activates Cdc2-cyclin B to trigger entry into mitosis. Cdc25C is itself regulated by phosphorylation. In asynchronously growing HeLa cells, we have determined that serine 216 is the major site of Cdc25C

We have purified the type I restriction enzymes SB and SP from Salmonella typhimurium and S. potsdam, respectively, and determined the DNA sequences that they recognize. These sequences resemble those previously determined for the type I enzymes, EcoB, EcoK and
The EcoA restriction enzyme from Escherichia coli 15T- has been isolated. It proves to be an unusual enzyme, clearly related functionally to the classical type I restriction enzymes. The basic enzyme is a two subunit modification methylase. Another protein species
Two polynucleotide-dependent ATPases, 95 and 181 kDa in size, have been purified to near homogeneity from cell-free extracts of Schizosaccharomyces pombe. Despite their size differences, their biochemical properties were strikingly similar. Both enzymes were capable of unwinding RNA and DNA
