Glycosylation-Mediated Functional Remodeling of PYCR1 in Natural Product Biosynthesis
Glycosylation-Mediated Functional Remodeling of PYCR1 in Natural Product Biosynthesis
1. Literature Information
Title: PYCR1: How glycosylation modification reshapes the biosynthetic pathways of natural products
Keywords: PYCR1, glycosylation, post-translational modification, natural product biosynthesis, [4+2] cycloaddition, enzyme catalysis
2. Research Background
The biosynthesis of complex natural products with multiple chiral centers and polycyclic skeletons has long been limited by insufficiently understood enzymatic mechanisms. Traditional prokaryotically expressed enzymes without glycosylation modifications show low catalytic efficiency and incomplete cyclization capabilities, making it difficult to realize the total synthesis of highly active target molecules. The functional regulation of biosynthetic enzymes via post-translational modifications, especially glycosylation, has become a frontier direction to break through such bottlenecks.
3. Research Approach
This study focused on the glycosylation modification of PYCR1 and systematically explored its role in natural product biosynthesis. The research strategy included:
Comparing the catalytic differences between glycosylated and non-glycosylated PYCR1
Analyzing the synergistic effect between glycosylation and calcium ion cofactors
Elucidating the structural basis of the tandem [4+2] cycloaddition reaction
Establishing an efficient eukaryotic expression system for functional enzymes
4. Key Research Outcomes
Glycosylation significantly enhances the catalytic efficiency of PYCR1 and enables novel tandem [4+2] cycloaddition activity.
PYCR1 acts as a calcium-dependent dual-functional cyclase, with its spatial configuration precisely regulated by glycosylation.
Glycosylation optimizes substrate binding and catalytic microenvironment, supporting multi-step continuous cyclization reactions.
This mechanism provides a new paradigm for the efficient synthesis of complex natural products.
