Introduction

Thermophilic archaea, which grow at extreme temperatures up to 110 and at the peak of extreme pH, are a remarkable source of stable enzymes (extremozymes). Extremozymes are highly valued in industrial processes for their ability to maintain functionality under extreme heat, pH, and solvent conditions, making them crucial for sectors like pharmaceuticals, biofuels, and chemical synthesis. Thermophilic archaea, despite being the most extant form of living organisms, are being studied to a limited extent, as compared to mesophilic organisms. Thermophilic enzymes are generally better than the other enzymes, as they exhibit proteins with unique attributes, and many of them function properly at 120 °C, at extremes of pH, and in the presence of organic solvents. Directing the synthesis of commercially valuable products specifically for the food, beverage, chemical

Thermophiles are microorganisms that exist at immensely high temperatures, usually exceeding 80 °C, and have been a central focus of scientific research due to their strong commercial applications.^1,2 Among these, Metallosphaera sedula strikes as a laboratory organism for analyzing biomining and carbon fixation in severe environments.³ This Thermoproteota elucidates exceptional adaptability, adapting unique metabolic pathways to sustain in acidic and high-temperature conditions.⁴ Some of the important enzymes secluded from M. sedula are DNA polymerase IV and adenylyl cyclase, which play a pivotal role in its carbon fixation mechanisms.^5,6 These enzymes are highly productive, helping the organism to acclimate inorganic carbon even within severe ecological patterns.⁷ Current genomic and proteomic research has provided detailed perceptions into the composition and function of the enzymes, summiting their potential for biotechnological roles, such as CO₂ fixation and biofuel production.^8,9

Furthermore, the hardiness and strength of M. sedula and its enzymatic machinery make it an excellent aspirant for bioleaching functions, where it can aid the extraction of important metals from unrefined rocks.^3,10 This ability underscores the organism’s significance in developing sustainable industrial practices. Despite the known capabilities of M. sedula, there is limited research on its enzyme-specific functions and industrial potential, which this study aims to address by characterizing key enzymes involved in biomining and carbon fixation. The biotechnological potential of M. sedula extends to industries such as biofuels and metal extraction, where its enzymes could revolutionize processes by enhancing efficiency and sustainability.

DNA Polymerases

DNA polymerases are the enzymes that replicate the genetic information in nucleic acids. So, they are required to copy the genetic makeup of every living thing and retain the stability of the genome throughout the life of the organisms.¹¹ Thermostable DNA polymerase is required in biotechnological applications and molecular biology techniques.¹² Any living organism at any cellular level that uses DNA as its heredity material possesses any form of thermostable DNA polymerases.¹³ There are almost ¹⁴ DNA-dependant DNA polymerases, according to an estimate of the complete human genome, which is incredible.¹⁴ These include the widely accepted, high-profile enzymes performing the role of replicating the high proportion of genomic DNA, and eight or more specialized DNA polymerases have been discovered in the last 10 years.¹⁵

The newly tracked-down DNA polymerases’ functions are still being explicated.¹⁶ One of its most important roles is to allow the synthesis to recommence in spite of the DNA degradation that reduces the continuation of the DNA helicase.¹⁷ One of the basic areas of interest in the research world is the pursuit of newly discovered DNA polymerase, as the innovative characteristics of each thermostable DNA polymerase may result in the respective production of unique reagents.¹⁸ Protein engineering techniques for producing hybrid or non-natural DNA polymerase have substantially produced potential DNA polymerases for a large number of different industrial applications. In molecular biology, thermostable DNA polymerase is potentially being used for PCR techniques, i.e., Taq polymerase obtained from thermos aquaticus.¹⁹
