ORFs for the 2,3-diacylglucosamine-phosphate biosynthesis UDP-2 and 3-diacylglucosamine diphosphatase (RWLH04621) were also identified.
Pioneering studies identified inositol glycans generated from Trypanosoma brucei, which displayed insulin mimetic action inhibiting lipolysis, glucose 6 phosphatase, and fructose-1,6 diphosphatase, well-known insulin-mediated metabolic effects [48].
The commonest diagnoses were methyl malonic acIdaemia (n=2; 20%), non-ketotic hyperglycinaemia (n=7; 10%), fructose 1,6 diphosphatase deficiency (n=1; 10%), and biotinidase deficiency (n=1; 10%).
In particular, because phosphorylation of MKK3/6, an upstream enzyme that phosphorylates p38 [37], was not blocked (Figure 4(c)) and the protein level of phospho-p38 diphosphatase, MKP-1 [38], was not enhanced (Figure 4(d)), NGACP treatment seems to directly target MKK3/6, although a specific enzyme assay would be required to obtain better evidence.
The increase in the glycolytic enzyme fructose 1,6 diphosphatase increases the pentose phosphate pathway.
He demonstrated the first enzyme of the Golgi body (nucleoside diphosphatase).
The nucleoside diphosphates are converted to dianionic nucleoside monophosphates (used for the antiporter) and inorganic phosphate by a nucleoside diphosphatase. It is postulated that inorganic phosphate exits the ER/Golgi lumen via a specific transporter (Fig.
