Title: Innovative Contributions of Kotikanyadan Sreekrishna in Biotechnology
Introduction
Kotikanyadan Sreekrishna is a notable inventor based in Bartlesville, OK, known for his contributions to biotechnology and the development of human serum albumin (HSA) expression systems. With a total of four patents to his name, Sreekrishna has made significant strides in the field, particularly in utilizing Pichia pastoris for protein expression.
Latest Patents
Among Sreekrishna's latest innovations is a patented method titled "Expression of human serum albumin in Pichia pastoris." This invention focuses on expression cassettes that include a 5' regulatory region derived from one of the Pichia pastoris AOXI, p40, DASI, or HIS4 genes, which are operably linked to an HSA structural gene featuring a specific signal sequence. The design ensures that the translational start codon is positioned within 0 to 11 deoxyribonucleotides from the 5' end of the HSA structural gene, also connected to a 3' termination sequence. Notably, the adenine and thymine content of the intervening deoxyribonucleotides ranges from approximately 55% to 64%. The expression cassette may function as either an autonomously replicating vector or an integrative vector. Additional embodiments include Pichia pastoris strains transformed with these HSA expression cassettes and methods for the effective secretion of HSA.
