Evaluation of methods for sequence analysis of highly repetitive DNA templates.

The DNA Sequencing Research Group (DSRG) of the ABRF conducted a study to assess the ability of DNA sequencing core facilities to successfully sequence a set of well-defined templates containing difficult repeats. The aim of this study was to determine whether repetitive templates could be sequenced accurately by using equipment and chemistries currently utilized in participating sequencing laboratories. The effects of primer and template concentrations, sequencing chemistries, additives, and instrument formats on the ability to successfully sequence repeat elements were examined.

N-myristoylation of Arf proteins in Candida albicans: an in vivo assay for evaluating antifungal inhibitors of myristoyl-CoA: protein N-myristoyltransferase.

Myristoyl-CoA: protein N-myristoyltransferase (Nmt) catalyses the covalent attachment of myristate to the N-terminal glycine of a small subset of cellular proteins produced during vegetative growth of Candida albicans. nmt447D is a mutant NMT allele encoding an enzyme with a Gly447-->ASP substitution and reduced affinity for myristoyl-CoA. Among isogenic NMT/NMT, NMT/ delta nmt and nmt delta/nmt447D strains, only nmt delta/nmt447D cells require myristate for growth on yeast/peptone/dextrose media (YPD) at 24 or 37 degrees C.
