Aglycone sterics-selective enzymatic glycan remodeling.

ABSTRACT: Precision remodeling of glycans in their native environments is pivotal for understanding glycan-mediated biological events and has important biotechnological implications in fields of clinical diagnosis, glyco-immune checkpoint therapy, and so forth. However, the influence of aglycone-steric diversity on the selectivity of glycan remodeling has been largely overlooked, limiting the application in complex biological scenarios. Here, we report the achievement of aglycone sterics-selective enzymatic glycan remodeling by controlled grafting of functional polymers from glycoenzyme. Through tuning polymer length, a series of enzyme-polymer composites with varying substrate permeability are prepared, which afford an activity pattern-based differentiation strategy for aglycone sterics. This leads
