In the annals of Indian science, few figures have embodied the nation’s march towards scientific excellence with such steadfastness as renowned biochemist Govindrajan Padmanabhan, who was recently recognized with the first Vigyan Ratna Puraskar, arguably the country’s most prestigious science award.
Padmanabhan’s contributions to biochemistry and molecular biology have been as understated as they have been profound and have done much to shape the contours of Indian biochemistry. Though he has already been feted with the Padma Shri (1991) and Padma Bhushan awards (2003) as well as the Shanti Swarup Bhatnagar Prize (1983), and his life’s work has reshaped Indian biochemistry, Padmanabhan has largely eschewed the spotlight.
It was only when President Droupadi Murmu conferred the 86-year-old with the Vigyan Ratna award earlier this week that Padmanabhan, a former director and towering figure at Bengaluru’s Indian Institute of Science (IISc), came into the spotlight again. He was born in 1938 in a small Tamil Nadu village, a world drastically apart from the scientific hubs he would later frequent. But Padmanabhan, who came of age with newly independent India, was consumed by a relentless pursuit of knowledge.
From his early days at the IISc, where he completed his doctorate, to his tenure as one of the institution’s most revered figures, his career has been defined by a quiet tenacity. His early foray into microbial genetics laid the groundwork, but it was his pivot to biochemistry that solidified his standing in the scientific community.
It was in the world of molecules that Padmanabhan found his true calling. His research into gene regulation and protein synthesis garnered acclaim, but it was his work on malaria—particularly the biochemistry of the parasite Plasmodium falciparum—that would cement his standing within the scientific community. His leadership turned the Department of Biochemistry at IISc into a hub of research and innovation, fostering an environment where intellectual curiosity thrived alongside rigorous scientific methodology.
Padmanabhan’s investigations into heme metabolism within the malaria parasite offered new pathways for treatment, placing India at the forefront of global malaria research.His research has advanced our understanding of how certain proteins, crucial for processing drugs in the body, are made and regulated (notably his work on the regulation of the biosynthesis of cytochrome P-450 and cytochrome oxidase). This work is significant in uncovering the molecular details of how our bodies break down and metabolize medications.
It was Padmanabhan who was instrumental in ushering in recombinant DNA technology in the country. Recombinant DNA technology is a method that allows scientists to combine DNA from different sources, creating new genetic material with desired traits and is the foundation of modern genetic engineering. Yet, he was a scientist first, a public figure only by necessity.
Despite his numerous accolades, Padmanabhan remained a humble and approachable figure, dedicated to the advancement of science for the greater good. He was a tireless advocate for better funding and support for scientific research in India, being thoroughly familiar with the roadblocks posed by bureaucratic hurdles and inconsistent financing. The trailblazing biochemist has steadfastly resisted the temptations of moving to the West, harbouring a deep conviction that science in India should not merely mimic Western practices but carve its own path, tailored to the country’s unique challenges.
This belief led him to decline directorship offers at international research centers, keeping him rooted in Bangalore to his beloved IISc. Even after retiring as the Director of IISc, Padmanabhan’s commitment to science did not wane. He continued to engage in research, mentor young scientists, and contribute to public debates on critical issues, such as India’s nuclear weapons program and genetically modified crops.
In his sunset years, Padmanabhan represents a model of scientific rigor, intellectual curiosity, and dedication to the public good. As India continues to carve out its place in the global scientific community, it stands on the shoulders of giants like Govindrajan Padmanabhan—a quiet pioneer whose work speaks louder than words.
