Improved Model of a LexA Repressor Dimer Bound to recA Operator
(ADENINE PRESS, 2004-04)complete three dimensional model for the LexA repressor dimer bound to the recA operator site consistent with relevant biochemical and biophysical data for the repressor was proposed from our laboratory when no crystal ... -
pH-dependent autocleavage of lambda repressor occurs in the operator-bound form: characterization of lambda repressor autocleavage
(PORTLAND PRESS, 2004-04-15)The first-order rate constants for the RecA-independent, spontaneous, pH-dependent autocleavage of the lambda cl repressor was measured in the present study at pH 10.6 at 27, 37 and 42 degreesC respectively. Autocleavage ... -
Three-dimensional models of NB-ARC domains of disease resistance proteins in tomato, arabidopsis, and flax
(ADENINE PRESS, 2008-02)Three dimensional models of NB-ARC domains in five different proteins were constructed based on the recently published crystal structure of the apoptotic protease activating factor 1, of which two are for tomato species, ... -
Digestion of the lambda cI Repressor with Various Serine Proteases and Correlation with Its Three Dimensional Structure
(ADENINE PRESS, 2008-12)Partial proteolysis of the lambda cl repressor has been carried Out systematically with trypsin. chymortrypsin, elastase, endoproteinase Glu-C, kallikrein, and thrombin. The cleavage sites have been determined by (i) ... -
RecA-Mediated Cleavage of lambda cI Repressor Accepts Repressor Dimers: Probable Role of Prolyl Cis-Trans Isomerization and Catalytic Involvement of H163, K177, and K232 of RecA
(ADENINE PRESS, 2009-10)The λ cI repressor is found to be cleaved in the presence of activated RecA in its DNAbound dimeric form at a rate similar to that in the absence of operator DNA in contrast to previous studies inferring repressor monomer ...
