Hot springs as a Source for Studying Rhomboid Protease Genes and Inhibitors in Silico Study

Rhomboid proteases (Rho) are affected by amino acid composition, protein structure, oligomerization, strong contacts, salt bridges, and bonding patterns. Protein tertiary structure can change with a single amino acid substitution. Rhomboids cleave misfolded membrane substrates. They help signal growth factors, maintain mitochondrial homeostasis, regulate protein quality, and invade parasites. Studying these proteins and their inhibitors will improve the medication targeting of this rhomboid protease, which is involved in the pathophysiology of numerous disorders like type II diabetes and Parkinson's. Their importance in eukaryotes is widely known, but their involvement in bacterial physiology is not. Rho genes are studied using Hot Springs metagenomic samples. JGI and IMG provided thermophilic protease sequences. MAFFT-aligned sequences. InterProScan examined every protein domain, whereas ProtParam calculated protease amino acid frequencies. I-TASSER predicts three-dimensional protein structures; CB-Dock, and Discovery Studio simulate and dock. Hot spring isolates in rhomboid gene alignments hindered the protein's evolution at high temperatures. Isolations conserved amino acid composition and active domains. Rhomboids' fundamental structure and functional locations have stayed intact across most life forms, preserving their proteolytic action. Asn 62, Trp 57, Ile 143, Phe (61, 100), Leu 99, and Arg 284 were critical in hot spring Rho genes. The fact that Rho inhibitors are active on hot spring rhomboids suggests that the enzyme has maintained a high degree of structural and functional homogeneity despite its presence in hot environments.
