Amino acids are the fundamental building blocks of proteins and play a pivotal role in various biological processes. Amino acid biosynthesis is a complex and highly regulated set of biochemical pathways through which organisms synthesize these essential compounds. The advantages of synthesizing amino acids using synthetic biology methods include:

  • Sustainability. Amino acid biosynthesis offers a sustainable alternative to traditional methods of amino acid production, such as extraction from natural sources or chemical synthesis.
  • Purity and Quality. Through controlled fermentation processes, we can achieve high levels of purity and quality in the synthesized amino acids.
  • Cost Efficiency. Over time, advances in biotechnology have made amino acid biosynthesis increasingly cost-effective. This translates to competitive pricing for our clients while maintaining product quality.

Amino Acid Biosynthesis Pathway

Amino acid biosynthesis involves a series of enzymatic reactions organized into specific pathways. These pathways are intricate and differ for each amino acid. However, some common principles apply:

Types of Amino Acids We Can Biosynthesize

Our synthetic biology technology enables us to biosynthesize a wide range of amino acids, including but not limited to:

  • Essential Amino Acids. These are amino acids that the human body cannot synthesize independently and must be obtained through diet or supplementation. Examples include lysine, leucine, and valine.
  • Non-Essential Amino Acids. These amino acids can be synthesized by the human body, but their availability through biosynthesis allows for applications in various industries. Examples include glutamine, glycine, and serine.
  • Conditional Amino Acids. These amino acids are typically non-essential but become essential under certain conditions, such as illness or stress. Examples include arginine and tyrosine.
  • Specialty Amino Acids. Some amino acids have specific applications in industries like pharmaceuticals, cosmetics, and food production. Examples include cysteine, tryptophan, and aspartic acid.
