espejiana BAL 31 upon the superhelix density (a) of the DNA has been examined.  ...  Positively supercoiled DNA is concluded not to contain regions having significant single-stranded character until values of a are reached which are very much higher than the values of -a for which negatively  ...  Alteromonas espejiana BAL 31 (American Type Culture Collection 29659; see ref. to Chan et al. in title footnote) produces extracellularly a nuclease which is very highly specific for single-stranded DNA  ...
