Latest Patents

Prasanna Vasu holds a patent for a thermally-tolerant pectin methylesterase (TT-PME). This enzyme is vital for its impact on the quality and processing properties of fruit and vegetable food products. The patent details the purification of TT-PME from sweet orange finisher pulp and the determination of its complete nucleic acid sequence. The purified enzyme was analyzed using SDS-PAGE, revealing two doublet bands with molecular masses of approximately 46,000 Da and 56,000 Da. Direct Edman sequencing indicated a common N-terminal peptide, while de novo sequencing of TT-PME tryptic peptides provided additional internal sequences. Notably, TT-PME does not correspond to any previously reported PME sequences, indicating it is a distinctive new isoform.
