We further present some semi-discrete modifications to the cubically convergent iterative methods derived by Kanwar and Tomar (Modified families of Newton, Halley and Chebyshev methods, Appl. Math. Comput. and derived a number of interesting new classes of third-order multi-point iterative methods free from second derivatives. Furthermore, several functions(More)
EngA, a unique GTPase containing a KH-domain preceded by two consecutive G-domains, displays distinct nucleotide binding and hydrolysis activities. So far, Escherichia coli EngA is reported to bind the 50S ribosomal subunit in the guanosine-5'-trihosphate (GTP) bound state. Here, for the first time, using mutations that allow isolating the activities of the(More)
HflX is a GTP binding protein of unknown function. Based on the presence of the hflX gene in hflA operon, HflX was believed to be involved in the lytic-lysogenic decision during phage infection in Escherichia coli. We find that E. coli HflX binds 16S and 23S rRNA - the RNA components of 30S and 50S ribosomal subunits. Here, using purified ribosomal(More)
EngA is an essential protein involved in ribosome biogenesis. It is an unique GTPase, possessing two consecutive G-domains. Using sequence and phylogenetic analysis, we found two intriguing variants among EngA homologues - one with a shorter linker joining the G-domains and another with a longer linker, which additionally possesses an extended C-terminus.(More)
