The replication region of the lactococcal plasmid pCI2000 was subcloned and analyzed. The nucleotide sequence of one 5.6-kb EcoRI fragment which was capable of supporting replication when cloned on a replication probe vector revealed the presence of seven putative open reading frames (ORFs). One ORF exhibited significant homology to several replication(More)
The nucleotide sequence of the Leuconostoc lactis 533 cryptic plasmid pCI411 (2926 bp) was determined. Analysis revealed the presence of three open reading frames (ORFs). ORF 1 was capable of encoding a 24.9 kDa peptide which shared homology with the replication initiation protein (RepB) from a number of Gram-positive rolling circle plasmids. ORF 2 could(More)
A number of non invasive methods have been developed to characterize parameters in near-surface skin tissue; however, the work has usually been concerned with using either spectral or spatial information. This motivated our study in which both spatial and spectral data are used to extract features for characterizing the spatial distribution of near-surface(More)
A mitochondrial type I-like, ATP-independent, DNA topoisomerase, isolated from highly purified yeast mitochondria, is genetically related to nuclear topoisomerase I. We found that the mitochondrial topoisomerase activity cannot be detected in yeast mitochondrial extracts prepared from strains in which the topoisomerase I gene (TOP1) is disrupted. Thus, the(More)
The emergence of compact optical spectral imaging technologies has motivated the study of their use in a variety of applications, including medical diagnosis and monitoring. In particular, large format CCD focal planes in conjunction with spectrally tunable devices offer enhanced spatial information together with visible and near infrared (NIR)(More)
