NMR in the SPINE Structural Proteomics project.

This paper describes the developments, role and contributions of the NMR spectroscopy groups in the Structural Proteomics In Europe (SPINE) consortium. Focusing on the development of high-throughput (HTP) pipelines for NMR structure determinations of proteins, all aspects from sample preparation, data acquisition, data processing, data analysis to structure determination have been improved with respect to sensitivity, automation, speed, robustness and validation. Specific highlights are protonless (13)C-direct detection methods and inferential structure determinations (ISD). In addition to technological improvements, these methods have been applied to deliver over 60 NMR structures of proteins, among which are five that failed to crystallize. The inclusion of NMR spectroscopy in structural proteomics pipelines improves the success rate for protein structure determinations.

Pregnancy and alpha-1 antitrypsin deficiency.

A 29 year old patient with alpha-1 antitrypsin deficiency and bullous emphysema became pregnant against the advice of her physicians. Despite a mid-trimester pneumothorax requiring the insertion of a chest tube, she went on to deliver a healthy child under epidural anaesthesia using a midforceps technique. Vaginal delivery is not necessarily contra-indicated in multiparous patients with bullous emphysema.

Incidence of Legionnaires' disease in a district general hospital.

In order to assess the incidence of Legionnaires' disease in a district general hospital, 90 consecutive patients with pneumonia seen over a 3-year period were investigated. Only 2 patients were found to have Legionnaires' disease, indicating that it is not a frequent cause of pneumonia in the Bristol area.

Colorimetric enzymatic determination of serum total carbon dioxide, as applied to the Vickers Multichannel 300 discrete analyzer.

Phosphoenolpyruvate carbosylase (EC 4.1.1.31) has been used in developing a simple, inexpensive colorimetric assay for serum total carbon dioxide in an open system. The oxaloacetate formed by the action of the enzyme on bicarbonate and phosphoenolpyruvate is measured by use of the diazonium salt of Fast Violet B. Interferences from billirubin, pyruvate, and drugs are negligible. Acetoacetate interference is significant only in highly ketotic samples, and a serum blank corrects for it. Serum protein interference is equivalent to 3.3 plus or minus 1.25 mmol of CO2 per liter and hence is sufficiently constant to be corrected for by use of a serum standard or serum blank. The method has been applied to the Vickers M-300 and D-300 systems and within-batch standard deviations of plus or minus 0.1 to plus or minus 0.6 mmol/liter have been observed. Excellent correlation with orthodox techniques has been obtained.
