Part:BBa_K4275037

pLAC4-KmarxMFα-TaLPMO-t-tTDH1

The composite part includes K. marx mating factor alpha (BBa_K4275000) and cellulase booster TaLPMO-t fused with type I dokerin for the assembly of cellulosome complex.

The fusion of K. marx mating factor alpha is used in order for the target TaLPMO-t cellulase booster to be secreted from our host yeast, which would be anchored on scaffold protein and assembled into the cellulosome complex.

Usage and Biology

Kluyveromyces marxianus mating factor alpha act as a secretion signal in Kluyveromyces marxianus. The mating factor alpha fuses an alpha mating factor domain onto TaLPMO-t. The signal peptide on the domain would direct the TaLPMO-t into RER and Golgi body, enabling the designated cellulase booster to be secreted by Kluyveromyces marxianus.

TaLPMO-t is a cellulase booster with type I dokerin fused on its C terminal to convert the protein from free booster enzyme into cellulosomal mode. As a copper-dependent enzyme, TaLPMO-t oxidizes and cleaves glycosidic bonds in cellulose, which significantly boosts the efficiency of crystalline cellulose degradation.
