Sino Biological's Role in Protein Design Enhancement

Sino Biological, Inc., listed on the Shenzhen Stock Exchange under the symbol 301047.SZ, has made significant strides in the field of genetic synthesis and protein expression. Recently, their cell-free protein synthesis workflow was employed in a groundbreaking study by Tencent’s AI for Life Sciences Lab, which was published in Nature Communications. This collaboration emphasizes the utility of Sino Biological's technology in facilitating rapid validation of AI-designed proteins that exhibit enhanced activity, stability, and multifunctionality.

Bridging AI Protein Design and Experimental Validation

While artificial intelligence has revolutionized the design of amino acid sequences in proteins, transforming these computer-generated designs into functional proteins continues to pose a formidable challenge in the realm of protein engineering. Factors such as protein activity, stability, folding, and expression are influenced by intricate structural and biochemical variables. This complexity often results in disparities between computational predictions and experimental outcomes.

To tackle this issue, the study introduced an Ontology Reinforcement Iteration (ORI) framework. This innovative system integrates protein ontology with reinforcement learning, leveraging feedback from laboratory experiments. By continuously feeding experimental data, such as protein expression levels and functional activity, back into the model, the team was able to iteratively optimize protein sequences, enhancing design accuracy.

Quick Turnaround with Cell-Free Synthesis

Utilizing Sino Biological's XPressMAX™ Cell-Free Protein Synthesis Kit, researchers were able to achieve rapid protein expression and functional screening. By cloning coding sequences into the kit's expression vector and incorporating them into a proprietary cell-free reaction system, teams could conduct quick cycles of design, construction, and testing. This facilitated the development of a lysozyme with over 100 times the activity of its natural counterpart, a heat-stable chitinase that maintains activity at 85 °C, and bifunctional enzymes that demonstrate improved yields compared to naturally occurring multifunctional enzymes.
