Part:BBa_K1298004
Added by LZU-HS-China-A
For the measurement of binding capacity
we took 2 μmol/L of chitinase in 50 mmol/L phosphate buffer (pH=8) and mixed thoroughly at 4°C (assuming no degradation), reacted for 1 h on a rotary mixer, 10,000 r/min for 5 min and collected the supernatant, which was the unbound protein, by Protein concentration was measured by the BCA method.
For the measurement of chitinase activity
chitinase is able to hydrolyse chitin to produce N-acetylglucosamine, which further reacts with 35-dinitrosalicylic acid to produce a brownish-red compound with a characteristic absorption peak at 540 nm, and the activity of chitinase can be characterised by the change in absorbance value.
PgeChia 1-1 (insert) using J04500
This part contains an RBS (BBa_B0034), a promoter (lacI inducible; BBa_R0010), and a coding region (PgeChia 1-1; BBa_K1298001). It is in a pSB1C3 backbone. With this, the chitinase protein is created. Chitinase breaks down chitin, a substance found in the exoskeleton of arthropods (spiders, insects, etc.) and in the cell walls of fungi. It should be noted that there is no secretory tag, meaning that the chitinase protein is not being secreted outside of the cell, but staying inside. The part should be used to have the chitinase protein break down chitin.
