| homology of a plasmid from the spirochete treponema denticola with the single-stranded dna plasmids. | the 2,647-bp nucleotide sequence of cryptic plasmid ptd1, isolated from the oral spirochete treponema denticola, was determined. the sequence revealed two open reading frames, a and b, which encode polypeptides of 335 and 235 amino acids, respectively. open reading frame a shows sequence similarity to genes that encode replication proteins from a group of plasmids common in gram-positive bacteria, which replicate via a single-stranded intermediate. | 1992 | 1339420 |
| distribution of the is elements iss1 and is904 in lactococci. | a broad distribution of the lactococcal is elements iss1 [1] and is904 [2] in several lactococcal plasmids and chromosomal dna was observed. hybridization of the iss1 and is904 oligonucleotide gene probes with dna of lactococcal phages showed that none of these tested bacteriophages contained one of the is elements. on the transductionally shortened lactose plasmid ptd1 an insertion sequence homologous to iss1 was identified closely downstream to the p-beta-galactosidase gene. sequence analysis ... | 1991 | 1653170 |
