Custom Crocetin Glucosyltransferase Production Workflow

Gene Optimization & Synthesis
We carry out codon optimization on the crocetin glucosyltransferase gene sequences. This optimization is tailored to guarantee the highest possible level of gene expression within the specific host organism you select, laying a solid foundation for efficient enzyme production.

Vector Construction & Transformation
Our team engineers high-copy-number plasmids with precision. These plasmids are then transformed into our exclusive, hyper - secretory microbial strains. These strains have been carefully developed to enhance the secretion of the target enzyme, thereby facilitating easier downstream purification processes.

Fermentation & Scaling
Utilizing pilot - scale bioreactors ranging from 10 L to 100 L, we embark on an optimization of induction parameters. This includes fine - tuning the temperature and pH depending on the host system. Through this meticulous optimization, we aim to maximize the yield of soluble protein, ensuring a high - quality product.

Affinity Purification
We employ a multi-step chromatography approach, incorporating size exclusion chromatography (SEC), ion exchange chromatography (IEC), and affinity chromatography. This combination of techniques enables us to achieve an enzyme purity level exceeding 95%. Additionally, it effectively removes all host - cell proteins and DNA, ensuring the safety and quality of the final enzyme product.

Activity Validation
Each batch of the produced enzyme undergoes a standardized enzymatic assay. In this assay, we use UDP - glucose and crocetin as substrates to accurately verify the Michaelis - Menten constant (Km) and maximum reaction velocity values. This rigorous validation step guarantees the consistent activity and performance of the enzyme, meeting your specific requirements for custom production.
