What to know about Engineered lipase could improve production of higher-value specialized lipids

An international research team has engineered a lipase enzyme (variant I291Y) that can selectively hydrolyze palmitic C16 acyl chains over oleic C18 acyl chains. The study, published in Bioresource Technology, utilizes computational design and microfluidic testing to demonstrate potential applications in food and pharmaceutical lipid modification.

What happened

Engineered lipase could improve production of higher-value specialized lipids Lisa Lock Scientific Editor Alexander Pol Deputy Editor Food and pharmaceutical manufacturers increasingly seek lipids with carefully controlled fatty-acid compositions.

Why it matters

However, natural oils usually contain mixtures of closely related fatty acids, and conventional enzymes often cannot distinguish reliably between them.

Common ground

An international research team has now engineered a lipase that preferentially hydrolyzes palmitic C16 acyl chains over oleic C18 acyl chains, even though the two differ by only two carbon atoms.
