Hansenula Polymorpha TERT: 
A Telomerase Catalytic Subunit Isolated in Recombinant Form with Limited Reverse...

Area of Science:

• Molecular Biology
• Biochemistry
• Genetics

Background:

• Telomerase synthesizes telomeres, crucial for eukaryotic chromosome stability.
• Investigating telomerase structure and function is hindered by difficulties in isolating its catalytic subunit.

Purpose of the Study:

• To develop a method for isolating recombinant telomerase reverse transcriptase.
• To assess the activity of the isolated catalytic subunit.

Main Methods:

• Isolation of recombinant telomerase reverse transcriptase from thermotolerant yeast Hansenula polymorpha.
• Functional testing of the isolated protein using an RNA/DNA duplex.

Main Results:

• Successfully isolated recombinant telomerase reverse transcriptase.
• The isolated catalytic subunit demonstrated limited reverse transcriptase activity.

Conclusions:

• The developed method enables the isolation of functional telomerase reverse transcriptase.
• The isolated subunit exhibits catalytic activity, though limited, providing a basis for further structural and functional studies.
