Experimental proteome analysis was combined with a genome-wide prediction screen to characterize the protein content of the thylakoid lumen of Arabidopsis chloroplasts. Soluble thylakoid proteins were separated by two-dimensional electrophoresis and identified by mass spectrometry. The identities of 81 proteins were established, and N termini were sequenced to validate localization prediction. ...

Peptidyl-prolyl cis/trans isomerases (PPIases) are an enzyme family which catalyse the isomerisation of proline peptide bonds to promote folding and re-folding peptides proteins. Three subfamilies have been identified: cyclophilins, FK506-binding proteins parvulins. Individual PPIases overexpressed in a number cancers [62], members targetted for immunosuppressant effects.

Phosphoglucose isomerase (D-glucose 6-phosphate ketol isomerase, EC 5.3.1.9) of the human erythrocyte was resolved into a major and two minor components. The major enzyme form, isomerase a, was purified to constant specific activity and appeared homogeneous bjl chromatography, electrophoresis, and ultracentrifugation. The minor enzyme forms, isomerases b and c, were also prepared in high purity...

A gene cluster encoding five enzymes of the mevalonate pathway had been cloned from Streptomyces sp. strain CL190. This gene cluster contained an additional ORF, orfD, encoding an unknown protein that was detected in some archaebacteria and some Gram-positive bacteria including Staphylococcus aureus. The recombinant product of orfD was purified as a soluble protein and characterized. The molecu...

Here, we report the identification of a metastasis promoting factor by a forward genetic screen in mice. A retroviral cDNA library was introduced into the nonmetastatic cancer cell line 168FARN, which was then orthotopically transplanted into mouse mammary fat pads, followed by selection for cells that metastasize to the lung. The genes encoding the disulfide isomerase ERp5 and beta-catenin wer...

The xylA gene coding for xylose isomerase from the hyperthermophile Thermotoga neapolitana 5068 was cloned, sequenced, and expressed in Escherichia coli. The gene encoded a polypeptide of 444 residues with a calculated molecular weight of 50,892. The native enzyme was a homotetramer with a molecular weight of 200,000. This xylose isomerase was a member of the family II enzymes (these differ fro...
