Abstract

A method is presented in which the features of a Buerger-type mechanical precession camera can be simulated using an electronic area detector and a three-circle automated goniostat. The resulting display as viewed on a video monitor is very much like a conventional precession photograph. The detector is stationary which causes a distortion that is negligible for precession angles less than 10 degrees. The virtue of this new method is that a precession image may be collected very fast and the intensities of the reflections when displayed are already digitized. The usefulness of these features is presented through two familiar tasks: the determination of a new protein crystal space group and the evaluation of a heavy-atom derivative.

PurF-independent phosphoribosyl amine formation in yjgF mutants of Salmonella enterica utilizes the tryptophan biosynthetic enzyme complex anthranilate synthase-phosphoribosyltransferase.

In Salmonella enterica, the biosynthetic pathways for the generation of purines and the essential cofactor thiamine pyrophosphate branch after sharing five enzymatic steps. Phosphoribosyl amine (PRA) is the first intermediate in the common portion of the pathway and is generated from phosphoribosylpyrophosphate and glutamine by the PurF enzyme (phosphoribosylpyrophosphate amidotransferase). A null mutation in yjgF allows PurF-independent PRA formation by an unknown mechanism. The tryptophan biosynthetic enzyme complex anthranilate synthase-phosphoribosyltransferase, composed of the TrpD and TrpE proteins, was shown to be essential for PRA formation in strains lacking both yjgF and purF. The activity generating PRA in a yjgF mutant background has features that distinguish it from the TrpDE-mediated PRA formation shown previously for this enzyme in strains with an active copy of yjgF. The data presented here are consistent with a model in which the absence of YjgF uncovers a new catalytic activity of TrpDE.

Purification, characterization and crystallization of thermostable anthranilate phosphoribosyltransferase from Sulfolobus solfataricus.

Anthranilate phosphoribosyltransferase (TrpD; EC 2.4.2.18) from the hyperthermophilic archaeon Sulfolobus solfataricus (ssTrpD) was expressed in Escherichia coli, purified and crystallized. Analytical gel permeation chromatography revealed a homodimeric composition of the enzyme. The steady-state kinetic characteristics suggest tight binding of the substrate anthranilic acid and efficient catalysis at the physiological growth temperature of S. solfataricus. Crystals of ssTrpD diffract to better than 2.6 A resolution and preliminary X-ray characterization was carried out. The crystals are suitable for structure determination.

Introns act post-transcriptionally to increase expression of the Arabidopsis thaliana tryptophan pathway gene PAT1.

The expression of the Arabidopsis thaliana PAT1 gene, which encodes the tryptophan biosynthetic enzyme phosphoribosylanthranilate transferase, was investigated using translational fusions of the PAT1 promoter to the GUS reporter gene. Independent stably transformed A. thaliana lines containing a single copy of a fusion that includes the entire plastid transit peptide and the first two introns of PAT1 had on average 30 times more GUS enzyme activity than plants transformed with a construct in which GUS was fused a short distance downstream of the PAT1 start codon. Plants containing the construct without introns or leader peptide accumulated undetectable amounts of PAT1-GUS fusion protein and mRNA, even though the transcriptional rate of both fusion constructs was comparable. Fusions containing the entire transit peptide and either of the first two introns yield as much GUS activity as constructs containing both introns, but constructs containing the transit peptide but no introns give rise to much lower levels. Therefore, introns greatly enhance the expression of PAT1-GUS fusions, and they act post-transcriptionally to increase the steady-state level of mRNA.
