The algC gene (encoding phosphomannomutase) of Pseudomonas aeruginosa, similarly to the algD gene, is environmentally regulated through transcriptional activation of its promoter. This gene, like algD, has a long (244 bp) 5' untranslated leader region (5' UTR). Using transcriptional and translational algC::lacZ fusions, we show that even though the transcript levels are similar, the beta-galactosidase-specific activities of the translational fusions are much higher than those of the transcriptional fusions during the entire growth phase. Both the 5' UTR and the ribosomal-binding site are shown to be important for efficient translation of the algC mRNA.

From 10 patients with carbohydrate-deficient glycoprotein (CDG) syndrome due to phosphomannomutase (PMM) deficiency, out of 10 lysosomal enzymes, 7 enzyme activities were measured in serum and 9 in leukocytes. In serum there was a 2-fold to 4-fold increase in activity of beta-glucuronidase, beta-hexosaminidase, beta-galactosidase, and arylsulphatase A. In leukocytes, however, several enzymes had reduced activity, particularly alpha-fucosidase, beta-glucuronidase and alpha-mannosidase. These abnormalities could result from missorting, defective reuptake and/or reduced stability of the enzymes due to the defective glycosylation.
