Experimental characterization

Bioinformatic analysis

CDD analysis showed specific hits in glycosyl transferase family 2. This diverse family transfers sugar from UDP-glucose, UDP-N-acetyl-galactosamine, GDP-mannose, or CDP-abequose to a range of substrates. Protein BLAST further supports these findings and suggests that HfsL is most likely a family 2 glycosyltransferase, which has a domain very similar to the poly-beta-1,6-N-acetyl-D-glucosamine synthase domain of biofilm PGA synthase.

DeepTMHMM analysis suggests that the protein is likely globular and positioned on the inner side of the cell membrane. The AlphaFold 3 structure provides additional evidence supporting its globular shape. A pTM score above 0.5 suggests that the predicted overall structure may closely resemble the true protein fold, while ipTM indicates the accuracy of the subunit positioning within the complex. Values higher than 0.8 represent confident, high-quality predictions.

To sum up, HfsL is most probably a globular family 2 glycosyltransferase, responsible for N-acetyl-D-glucosamine transfer to the acceptor molecule, as is further verified by existing research. [1][2][3]
