ABSTRACT
|
|
|
| |
|
Weissella viridescens FemX (FemX(Wv)) belongs to the Fem family of nonribosomal
peptidyl transferases that use aminoacyl-tRNA as the amino acid donor to
synthesize the peptide cross-bridge found in the peptidoglycan of many species
of pathogenic gram-positive bacteria. We have recently solved the crystal
structure of FemX(Wv) in complex with the peptidoglycan precursor
UDP-MurNAc-pentapeptide and report here the site-directed mutagenesis of nine
residues located in the binding cavity for this substrate. Two substitutions,
Lys36Met and Arg211Met, depressed FemX(Wv) transferase activity below detectable
levels without affecting protein folding. Analogues of UDP-MurNAc-pentapeptide
lacking the phosphate groups or the C-terminal D-alanyl residues were not
substrates of the enzyme. These results indicate that Lys36 and Arg211
participate in a complex hydrogen bond network that connects the C-terminal
D-Ala residues to the phosphate groups of UDP-MurNAc-pentapeptide and constrains
the substrate in a conformation that is essential for transferase activity.

The most recent references are shown first.
Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
Where a reference describes a PDB structure, the PDB
