Functional and structural characterization of a serine protease from Bacillus toyonensis co-expressed with short peptides from late embryogenesis abundant (LEA) proteins

Ammar Khazaal Kadhim Almansoori, Nurul Ain Syukriyah, Choo Yi Hang, Mustafa Abdulfattah, Shinya Ikeno, Lo Hui Yu, Haider Mahmod Jasim, Rashidah Abdul Rahim

This work highlights a simple and effective approach to improve industrial proteases using short late embryogenesis abundant peptides as natural stabilizers. The method enhanced yield, thermal stability, and pH adaptability across acidic and alkaline conditions without genetic redesign of the protease itself, offering a broadly applicable and economical strategy for enzyme improvement.
