A: Yes. By selecting and engineering specific HAS isoforms and controlling the fermentation duration and precursor concentration, we can target precise molecular weight ranges tailored to your application.

Q: Q: Is your production process endotoxin-free?

A: Because we primarily utilize organisms like Bacillus subtilis, our process is inherently lower in endotoxins compared to traditional Streptococcus methods, making it ideal for injectable grades.

Q: Q: Do you offer cell-free synthesis options?

A: Absolutely. For projects requiring absolute monodispersity and the highest purity, we can implement a one-pot multi-enzyme synthesis system with nucleotide sugar regeneration.

Q: Q: What is the typical lead time for a custom enzyme project?

A: Lead times vary based on the complexity of the design, but typically range from 8 to 14 weeks from digital modeling to pilot-scale delivery. Contact us for a detailed project timeline.

Q: Q: Can you help with the regulatory documentation for submission?

A: Yes, Creative Biolabs provides comprehensive documentation, including batch records, purity analysis, and characterization data, to support your regulatory filings.

Introduction to Hyaluronic Acid Synthase (HAS)

HAS is a pivotal Glycan Tool Enzyme responsible for the biosynthesis of hyaluronic acid (HA), a critical glycosaminoglycan with diverse biological functions. In the realm of N-acetyl-β-D-glucosamine-(1→4)-[HA] production service, This Glycosyltransferase plays a central role by catalyzing the sequential addition of N-acetylglucosamine and glucuronic acid units, forming the characteristic HA polymer. This enzymatic precision enables tailored synthesis of HA with specific molecular weights and structural modifications, ensuring optimal performance in biomedical, cosmetic, and pharmaceutical applications.

Custom HAS Production Workflow

Computational Design & Enzyme Modeling
Harnessing cutting-edge structural bioinformatics and AI-driven algorithms, we simulate the HAS enzyme's active site dynamics to predict polymer elongation patterns and substrate specificity. This enables the rational design of enzyme variants with enhanced catalytic efficiency and tailored glycosidic linkage formation.

Metabolic Pathway Refactoring
We rewire microbial hosts using synthetic biology tools to divert metabolic flux toward sugar precursors. This metabolic engineering strategy ensures high intracellular availability of building blocks for HA biosynthesis.

High-Throughput Micro-Fermentation Optimization
Leveraging parallel 0.5 L-3 L bioreactor systems, we deploy design of experiments methodologies to systematically optimize induction timing, feed strategies, and dissolved oxygen levels. This accelerates the identification of optimal conditions for HAS expression and HA polymer accumulation.

Seamless Industrial Scale-Up
Our process engineering expertise ensures a smooth transition from lab to commercial-scale bioreactors, with real-time monitoring of critical parameters, such as oxygen transfer rate, and viscosity control to maintain product consistency.

Ultra-Pure Downstream Processing
Using advanced tangential flow filtration and ethanol precipitation techniques, we achieve host cell protein and DNA removal without compromising polymer integrity. Rigorous quality control ensures >99% purity and narrow molecular weight distribution.

What Makes Us Unique?

AI-Enhanced Precision Engineering
Our proprietary computational platform leverages artificial intelligence to de novo design HAS. These molecular rulers enable the synthesis of HA polymers spanning four orders of magnitude, delivering unprecedented control over chain length distribution and functional end-group modification.

Endotoxin-Free GRAS Production Systems
By employing non-pathogenic hosts, we eliminate the endotoxin contamination risks inherent in traditional Streptococcus-based processes. This streamlines regulatory approval while ensuring pharmaceutical-grade purity from bench to commercial scale.

Metabolic Flux Optimization
Beyond simple protein overexpression, our systems biology approach rewires host metabolism to create a dedicated sugar highway for sugar precursor overproduction. Simultaneously, we knock out endogenous hyaluronidases to prevent premature polymer degradation, ensuring maximum yield of intact high-molecular-weight HA.

Industrial-Scale Proven Performance
Our globally deployed biomanufacturing network routinely executes 10,000 L fermentation runs with documented yields exceeding 10 g/L of ultra-pure HA.
