Description L-threonine--uridine -5-aldehyde transaldolase (2.2.1.-)
Catalyzed reaction Uridine-5′-aldehyde + L-threonine = 5'-C-glycyluridine + acetaldehyde
Cofactor Pyridoxal-phosphate
LipK is an enzyme responsible for the CC bond-forming event during GlyU biosynthesis as an L-threonine:uridine-5′-aldehyde transaldolase.
The enzyme from Streptomyces sp. SANK 60405 has no activity with alternative amino acids such as glycine or serine as aldol donors, and acetaldehyde is a co-product.
