研究结论

Date Results Publications
2013-06-29 12:43:00 Poly(A)polymerase I participates in the ability of the bacteria to adapt to and survive detrimental conditions by constantly monitoring and adjusting to its environment. 23123524
2013-04-20 14:04:00 THe data demonstrates that regulation of PAP I is critical not for preventing the decay of mRNAs, but rather for maintaining normal levels of functional tRNAs and protein synthesis in E. coli, a function for polyadenylation that has not been observed previously in any organism. 23241393
2012-05-05 10:50:00 Characterization of RNA fragments that accumulate in a PNPase deficient strain showed that Glu tRNA precursors still harbouring the 5' leader can be degraded by a 3' to 5' quality control pathway involving poly(A) polymerase. 22142150
2010-01-21 00:00:00 There are three transcription start sites upstream of the pcnB coding sequence; activities of at least two of these promoters are in inverse correlation to bacterial growth rates. 16330100
2010-01-21 00:00:00 Data show that the inactivation of Hfq leads to a reduction in the ability of poly(A) polymerase I to add poly(A) tails to mRNAs containing Rho-independent transcription terminators. 15522076
