Lysozyme growth

Here, two different sequences from transth3Tetin were successfully combined into mixed fibrils [54], This is not always the case, however. For amyloidogenic proteins, the ability of other fibrils to act as cross-seeds for growth is known to depend on sequence similarity [55]. Seeding hen lysozyme solutions with seeds formed from closely related sequences (e.g. hen and other lysozymes) led to the largest increases in the rate of formation of fibrils. Consequently, there may be some restrictions on the selection of distinct peptide sequences to produce scaffolds.

Growth conditions in deep-well microtiter plates were optimized with respect to optimal expression of active enzymes (Fig. 2.2.1.1). The best results were obtained with an expression time of 20 h at 37 °C (Fig. 2.2.1.1, lanes 7-9). Subsequently, E. coli cells were enzymatically disrupted by lysozyme treatment, and the carboligase activity was monitored by a modified tetrazolium salt color assay [16], This color assay is based on the reduction of the 2,3,5-triphenyltetrazolium chloride (TTC) 13 to the corresponding formazan 15, which has an intense red color (Fig. 2.2.1.2A). Before screening ofa BFD variant library, substrates and products were tested in the color assay. Neither substrate, benzaldehyde 4 nor dimethoxy-acetaldehyde 8, reduced TTC 13 however, the product 2-hydroxy-3,3-dimethoxy-propiophenone 10 already caused color formation at low concentrations of 2.5-10 mM (Fig. 2.2.1.2B). Benzoin 12 as the product also gave a color change at a similar concentration (data not shown).

Schwartz et al. evaluated the use of fibre-optic probe dispersive Raman and PLS calibration to study crystallisation in a hanging drop experiment. They could show that the lysosome concentration could be monitored during the experiment through the concentration phase, nucleation and crystal growth [27], In later experiments, they were able to utilise in-line Raman data to control the concentration of lysozyme to affect the crystallisation path and thereby obtaining the desired large single crystals [28], The same setup was used for crystallisation of apoprotein. Also in this case the Raman data were used to control the evaporation and thus the supersaturation for optimised crystal size [29].

The culture is harvested by centrifugation at 5000 g and 4° at peak production. Lysozyme activity, which is monitored by the standard turbidity assay of culture supernatant (described in a later section), typically reaches its peak after 5 to 7 days of growth in rich medium. For inactive mutants, the peak of lysozyme secretion is estimated as 12 to 24 hr after the yeast cell density (monitored by A6S0) reaches its peak.
