Spatially Partitioned Engineering of an Alginate Lyase Overcomes the Stability–Activity Trade-Off via Distal Cap Loop Rigidification and Network Remodeling
The stability–activity trade-off limits engineering of alginate lyases for alginate oligosaccharide production. Here, a spatially partitioned semirational strategy coupled with the greedy accumulated strategy for protein engineering (GRAPE) was applied to an alginate lyase from Vibrio sp. The optimized variant M13 ac...
