Nonribosomal peptide synthetases (NRPS) are multi-domain enzymes that have innumerably beneficial health applications. Realizing the significance of marine microorganisms in search for NRPS sequences, study was conducted for analysis of NRPS gene sequences of marine crab haemolymph bacteria for the first time. Strains belonging to five different species were found to have NRPS genes. The study generated NRPS sequences from four bacterial species, for which NRPS gene information was not available earlier. Two new putative adenylation domain signatures were identified from phylum Firmicutes. In silico analysis of amino acid sequences from four species showed less identity (42-50%) to the characterized NRPS compounds that integrate serine residue in active site, suggesting the novelty or uncharacterized nature. Altogether, the study warrants future research exploiting marine crab haemolymph bacteria, an unexplored niche of microbial genetic wealth to discover microbial novel NRPS genes and natural products using emerging tools and technologies.

Engineering of nonribosomal peptide synthetases (NRPSs) could transform the production of bioactive natural product derivatives. A number of recent reports have described the engineering of NRPSs without marked reductions in yield. Comparative analysis of evolutionarily related NRPSs can provide insights regarding permissive fusion sites for engineering where recombination may occur during evolutionary processes.

Background: The marine environment boasts distinctive physical, chemical, and biological characteristics. While numerous studies have delved into the microbial ecology and biological potential of the marine environment, exploration of genetically encoded, deep-sea sourced secondary metabolites remains scarce. This study endeavors to investigate marine bioproducts derived from deep-sea water samples at a depth of 1,000 m in the Java Trench, Indonesia, utilizing both culture-dependent and whole-genome sequencing methods.

Background: Enhanced biological phosphorus removal (EBPR) systems utilize phosphorus-accumulating organisms (PAOs) to remove phosphorus from wastewater since excessive phosphorus in water bodies can lead to eutrophication. This study aimed to characterize a newly isolated PAO strain for its potential application in EBPR systems and to screen for additional biotechnological potential. Here, sequencing allowed for genomic analysis, identifying the genes and molecules involved, and exploring other potentials.
