The three-dimensional architecture of the class I ligase ribozyme (2004)

BERGMAN, NICHOLAS H., LAU, NELSON C., LEHNERT, VALERIE, WESTHOF, ERIC, BARTEL, DAVID P.

The class I ligase ribozyme catalyzes a Mg++-dependent RNA-ligation reaction that is chemically analogous to a single step of RNA polymerization. Indeed, this ribozyme constitutes the catalytic...

Position-Based Scanning for Comparative Genomics and Identification of Genetic Islands in Haemophilus influenzae Type b

Bergman, Nicholas H., Akerley, Brian J.

Bacteria exhibit extensive genetic heterogeneity within species. In many cases, these differences account for virulence properties unique to specific strains. Several such loci have been discovered...

Formation and Composition of the Bacillus anthracis Endospore†

Liu, Hongbin, Bergman, Nicholas H., Thomason, Brendan, Shallom, Shamira, Hazen, Alyson, Crossno, Joseph, ...

The Superoxide Dismutases of Bacillus anthracis Do Not Cooperatively Protect against Endogenous Superoxide Stress

Passalacqua, Karla D., Bergman, Nicholas H., Herring-Palmer, Amy, Hanna, Philip

The Bacillus anthracis chromosome encodes four unique, putative superoxide dismutase (sod) genes. During exponential growth and sporulation, sodA1, sodA2, and sodC are transcribed constitutively...
