Conjugative coupling proteins (CPs) are proposed to play a role in connecting the
relaxosome to a type IV secretion system (T4SS) during bacterial conjugation. Here we …

In preparation for transfer conjugative type IV secretion systems (T4SS) produce a
nucleoprotein adduct containing a relaxase enzyme covalently linked to the 5′ end of …

As in most bacteria, topological problems arising from the circularity of the two Vibrio
cholerae chromosomes, chrI and chrII, are resolved by the addition of a crossover at a …

Bacteriophage T4 homologous recombination events are promoted by presynaptic filaments
of UvsX recombinase bound to single-stranded DNA (ssDNA). UvsY, the phage …

The ability of conjugative plasmids from six different incompatibility groups to mobilize a set
of mobilizable plasmids was examined. The mobilization frequencies of plasmids RSF1010 …

TraI relaxase–helicase is the central catalytic component of the multiprotein relaxosome
complex responsible for conjugative DNA transfer (CDT) between bacterial cells. CDT is a …

MbeC is a 13-kDa ColE1-encoded protein required for efficient mobilization of ColE1, a
plasmid widely used in cloning vector technology. MbeC protein was purified and used for in …

ABSTRACT The Bacteroides conjugative transposon CTnDOT encodes an integrase,
IntDOT, which is a member of the tyrosine recombinase family. Other members of this group …

Site-specific recombination occurs at short specific sequences, mediated by the cognate
recombinases. IntA is a recombinase from Rhizobium etli CFN42 and belongs to the tyrosine …

The broad‐host‐range, multicopy plasmid R1162 is efficiently mobilized during conjugation
by the self‐transmissible plasmid R751. The relaxosome, a complex of plasmid DNA and …
