An endo-β-mannanase from T. virens UKM1 was successfully cloned and expressed as functionally active enzyme in P. pastoris.

class="label">•

Expressed recombinant mannanase (rMANTV) showed high optimum temperature at 70 °C.

class="label">•

It showed 70% of its activity at 80 °C and good stability along 20–65 °C.

class="label">•

rMANTV showed good thermotolerance with more than 60% of retaining activity at 60 °C up to one hour.

class="label">•

rMANTV has a half-life of 26 min at 70 °C.
