Molecular Microbiology, Volume 119, Issue 1, Page 44-58, January 2023., 2023 In this study, we found that excision of Escherichia coli CP4‐57 prophage inactivates trans‐translation and activates the ArfA/RF2 rescue pathway back to back. This “rescue‐switching” rearranges the intercellular proteome landscape and E. coli phenotype in a rescue‐associated proteolysis‐dependent manner.

Sequence motifs that distinguish ATP(CTP) : tRNA nucleotidyl transferases from eubacterial poly(A) polymerases [PDF]
, 2004 ATP(CTP):tRNA nucleotidyl transferases, tRNA maturing enzymes found in all organisms, and eubacterial poly(A) polymerases, enzymes involved in mRNA degradation, are so similar that until now their biochemical functions could not be distinguished by their

Kinetic studies on the phosphorolysis of polynucleotides by polynucleotide phosphorylase
Journal of Biological Chemistry, 1975 The kinetics of the phosphorolysis of polynucleotide (as differentiated from oligonucleotide) by polynucleotide phosphorylase of Micrococcus luteus has been investigated. Double reciprocal plots of initial velocity against either inorganic phosphate or polynucleotide concentration are linear, and furthermore, the affinity of the enzyme for either ...
