C. Di Franco et al., Molecular analysis of two rolling-circle replicating cryptic plasmids, pBMYdx and pBMY1, from the soil gram-positive Bacillus mycoides, PLASMID, 44(3), 2000, pp. 280-284
Two cryptic plasmids of two environmental strains of the soil Bacillus myco
ides were cloned and sequenced. They are of a small size (3377 and 3476 bp)
and carry regions homologous to double- and single-strand origins of repli
cation of rolling-circle replication modules. In addition, both plasmids ha
ve ORFs with homologies with Mob and Rep proteins, in the same relative pos
ition and orientation. While dso- and sso-like sequences are similar in pBM
Y1 and pBMYdx, the putative Mob and Rep proteins are not homologous between
the two but show similarity with Mob and Rep proteins of different bacteri
al plasmids (C) 2000 Academic Press.
