Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Shipping Information
Shipped: ?Freeze dried Z. mobilis containing the plasmid
Comments
Restriction digests of the clone give the following sizes (kb): AvaI--4.2, 2.8.
The GAP/xylA/xylB operon may be recovered as a 4.1 kb NotI fragment.
This strain containing pZB4 is useful for fermenting glucose and pentoses (xylose), produced by hydrolysis of cellulose and hemicellulose, to produce ethanol.
The xylA/xylB operon is controlled by the Z. mobilis glyceraldehyde-3-phosphate dehydrogenase (GAP) promoter.
The talB/tktA operon is controlled by the Z. mobilis enolase (ENO) promoter. The GAP and ENO promoters are in a head-to-head orientation.
Plasmid contains the GAP-xylA/xylB operon from pGapXKH in a clockwise orientation and ENO-tal/tkt operon from EnoTAL/TKT in a counterclockwise orientation.
This plasmid is shipped in Zymomonas mobilis CP4. It should be grown in Zymomonas media (20 g glucose, 10 g Yeast extract, 2 g KH2PO4 in one liter of distilled water) with 10 ug/ml tetracycline at 30C in an anaerobic gas mixture of 80%N2-10%CO2 - 10% H2.
