Title: Subramaniasastry Kozhalmannom Krishnan: Innovator in Peptide Research

Introduction

Subramaniasastry Kozhalmannom Krishnan is a notable inventor based in Karnataka, India. He has made significant contributions to the field of biological sciences, particularly in the area of peptide research. His work has led to the development of innovative solutions that have potential applications in various scientific domains.

Latest Patents

Krishnan holds a patent for a potassium channel modulator peptide, specifically a novel 13-residue peptide named Mo1659. This peptide is isolated from the venom of a cone snail. The research involved high-performance liquid chromatography (HPLC) fractions of the venom extract, which yielded an intense UV-absorbing fraction with a mass of 1659 Da. De novo sequencing was performed using matrix-assisted laser desorption and ionization and electrospray MS/MS methods, along with the analysis of proteolytic fragments. The amino acid sequence of Mo1659 was confirmed by comparison with the chemically synthesized peptide and conventional Edman sequencing. Notably, Mo1659 has an unusual sequence characterized by a preponderance of aromatic residues and the absence of apolar, aliphatic residues such as Ala, Val, Leu, and Ile. Furthermore, Mo1659 lacks disulfide bridges, distinguishing it from conotoxins, and bears no sequence similarity with any acyclic peptides isolated thus far from cone snail venoms. Electrophysiological studies indicate that Mo1659 targets non-inactivating voltage-dependent potassium channels, suggesting its potential utility in neurological research.
