Abstract


Transglutaminases have been found in various living organism, such as mammals, plants,
microorganisms, and marine organisms including fishes. Transglutaminases have many various functions
such as food properties, non-food properties and pharmacologies. This research aimed to characterize
transglutaminase that obtained from byproducts of yellow pike conger (Congresox talabon) such as
catadromous fish of yellow pike conger’s liver. The characteristic of transglutaminase had the possibility
to know the optimum condition in application of transglutaminase from liver of yellow pike conger such
as food processing industry, non-food industry and pharmacological application. A yield of yellow pike
conger’s liver was 0.88±0.11%. Specific activity of remang fish liver weighing 10 grams was 1,375 U/mg.
Characteristic crude transglutaminase from liver of yellow pike conger had optimum pH at 7.5; optimum
temperature at 50°C, transglutaminase activity increased on Mg
2+
 ion dependent and crude transglutaminase
had molecular weight of 27.48; 37.00; 69.51; 78.89; 88.18; 108.45; 134.10; dan 172.12 kDa.
