The expressional cassette was integrated into B. subtilis WB800 genome replacing 3’amyE-5’amyE, hindering the native amylase activity of the host. Expression of expected protein was confirmed by electrophoresis SDS-PAGE. From our results, it indicates that gene MTH was expressed successfully in B. subtilis WB800. After 0.5% acetoin induction for 48 h, the data showed that the protein with a molecular mass of ~64 kDa on SDS-PAGE was expressed. The level of recombinant protein in WBpAacoMTH was increased and reached 2.5%, 15.2% and 21.95%, respectively comparing with native B. subtilis WB800.

Module 9 - Virtual memory. Virtual memory can be a very interesting subject since it has so many different aspects: page faults, managing the backing store, page replacement, frame allocation, thrashing, page size. The objectives of this chapter are to explain these concepts and show how paging works.

In the present study, a novel pre-miniproinsulin analogue was designed to have a short 9 residue sequence replacing the 35 residue C-chain, one lysine and one arginine added to the C-terminus of the B-chain in combination with glycine and arginine substitution at A21 and B29, respectively, and a 16-residue fusion partner comprising the pentapeptide sequence (PSDKP) of the N-terminus of human tumor necrosis factor-a (TNF-a), 6 histidine residues for Ni2+ chelated affinity purification and a pentapeptide ending with methionine for ease of chemical cleavage fused at the N-terminus.

As detection of relationships improves with more samples and better methodology, families and super- families can become more populated. At present, structur- al relationships provide the highest level of classification, and structure-based databases classify proteins with similar ‘folds’. These classifications reveal that whenever structures are known for two proteins that are considered members of the same family or superfamily, the structures are similar, whereas the converse is often not true.

Terminal 2 was opened in 1960. Once again, the architect firm responsible was Vilhelm Lauritzen AS. Its simple layout as a large, centre-less space with inserted and replaceable floor slabs was designed to make it possible to carry out later conversions and extensions without bringing the terminal to a halt. In 1987, Vilhelm Lauritzen AS completed an extension of Terminal 2 with a large new shopping centre. The terminal has subsequently been converted and extended several times (see pages 16 and 24).
