Summary
Hyaluronan synthase (HAS) engineering is key for high-molecular-weight hyaluronic acid (HA) production. This study reviews HAS origins, structure, and modeling to improve HA biosynthesis for biomedical uses.
Area of Science:
- Biochemistry
- Enzymology
- Molecular Biology
Background:
- Hyaluronan synthase (HAS) synthesizes hyaluronic acid (HA), a crucial biopolymer with diverse applications.
- HAS is a membrane-bound enzyme critical for HA yield and molecular weight, with variations across sources impacting product properties.
- Industrial production of high-molecular-weight HA faces challenges in yield, consistency, and understanding HAS mechanisms.
Purpose of the Study:
- To systematically review HAS origins, phylogeny, and structure-function relationships.
- To explore potential mechanisms for high-molecular-weight HA synthesis using structural modeling.
- To highlight recent advances in HAS engineering for enhanced HA molecular weight production.
Main Methods:
- Phylogenetic analysis of HAS sequences.
- Structural modeling of HAS enzymes.
- Review of existing literature on HAS engineering and HA biosynthesis.
Main Results:
- Detailed review of HAS origins and evolutionary relationships.
- Identification of potential structural features influencing high-molecular-weight HA synthesis.
- Summary of current strategies for HAS engineering to boost HA molecular weight.
Conclusions:
- Understanding HAS structure and function is crucial for improving HA biosynthesis.
- HAS engineering holds promise for efficient industrial production of high-molecular-weight HA.
- This review provides a foundation for rational HAS design and enhanced HA production.

01:25Structure of Cadherins
5.3K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

01:05Proteoglycans
5.3K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

01:19Cadherins in Tissue Organization
4.6K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

01:02Role of Microtubules in Cell Wall Deposition
3.5K
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...
