Two putative genes, lip29 and est29, encoding lipolytic enzymes from the thermophilic bacterium Geobacillus thermocatenulatus KCTC 3921 were cloned and overexpressed in Escherichia coli. The recombinant Lip29 and Est29 were purified 67.3-fold to homogeneity with specific activity of 2.27 U/mg and recovery of 5.8% and 14.4-fold with specific activity of 0.92 U/mg and recovery of 1.3%, respectively. The molecular mass of each purified enzyme was estimated to be 29 kDa by SDSPAGE. The alignment analysis of amino acid sequences revealed that both enzymes belonged to GDSL lipase/esterase family including conserved blocks with SGNH catalytic residues which was mainly identified in plants before. While Est29 showed high specificity toward short-chain fatty acids (C4-C8), Lip29 showed strong lipolytic activity to long-chain fatty acids (C12-C16). The optimal activity of Lip29 toward p-nitrophenyl palmitate as a substrate was observed at 50°C and pH 9.5, respectively, and its activity was maintained more than 24 h at optimal temperatures, indicating that Lip29 was thermostable. Lip29 exhibited high tolerance against detergents and metal ions. The homology modeling and substrate docking revealed that the long-chain substrates showed the greatest binding affinity toward enzyme. Based on the biochemical and in silico analyses, we present for the first time a GDSL-type lipase in the thermophilic bacteria group.Parasites, and the diseases they cause, are important from an ecological and evolutionary perspective because they can negatively affect host fitness and can regulate host populations. Consequently, conservation biology has long recognized the vital role that parasites can play in the process of species endangerment and recovery. However, we are only beginning to understand how deeply parasites are embedded in ecological systems, and there is a growing recognition of the important ways in which parasites affect ecosystem structure and function. Thus, there is an urgent need to revisit how parasites are viewed from a conservation perspective and broaden the role that disease ecology plays in conservation-related research and outcomes. This review broadly focusses on the role that disease ecology can play in biological conservation. Our review specifically emphasizes on how the integration of tools and analytical approaches associated with both disease and molecular ecology can be leveraged to aid conservation biology. Our review first concentrates on disease mediated extinctions and wildlife epidemics. We then focus on elucidating how host-parasite interactions has improved our understanding of the eco-evolutionary dynamics affecting hosts at the individual, population, community and ecosystem scales. We believe that the role of parasites as drivers and indicators of ecosystem health is especially an exciting area of research that has the potential to fundamentally alter our view of parasites and their role in biological conservation. The review concludes with a broad overview of the current and potential applications of modern genomic tools in disease ecology to aid biological conservation.The developmentally active and cell-stress responsive hsrω locus in Drosophila melanogaster carries two exons, one omega intron, one short translatable open reading frame (ORFω), long stretch of unique tandem repeats and an overlapping mir-4951 near its 30′ end. It produces multiple long noncoding RNAs (lncRNAs) using two transcription start and four termination sites. Earlier cytogenetic studies revealed functional conservation of hsrω in several Drosophila species. However, sequence analysis in three species showed poor conservation for ORFω, tandem repeat and other regions while the 16 nt at 50 and 60 nt at 30 splice junctions of the omega intron, respectively, were found to be ultra-conserved. Citarinostat manufacturer The present bioinformatic study using the splice-junction landmarks in D. melanogaster hsrω identified orthologues in publicly available 34 Drosophila species genomes. Each orthologue carries a short ORFω, ultra-conserved splice junctions of omega intron, repeat region, conserved 30’end located at mir-4951, and syntenic neighbours. Multiple copies of conserved nonamer motifs are seen in the tandem repeat region, despite a high variability in the repeat sequences. Intriguingly, only the omega intron sequences in different species show evolutionary relationships matching the general phylogenetic history in the genus. Search in other known insect genomes did not reveal sequence homology although a locus with similar functional properties is suggested in Chironomus and Ceratitis genera. Amidst the high sequence divergence, the conserved organization of exons, ORFω and omega intron in this gene’s proximal part and tandem repeats in distal part across the Drosophila genus is remarkable and possibly reflects functional importance of higher order structure of hsrω lncRNAs and the small omega peptide.A relationship between the polymorphism in promoter region of the UGT1A1 gene and the development of jaundice has been demonstrated recently. This polymorphism leads to 30% of normal rate transcription initiation of UGT1A1 gene, thus decreasing the bilirubin glucuronidation. The combination of the G6PD deficiency and polymorphism in neonates and adults may causepronounced hyperbilirubinaemias. The aim of this study was to analyse the variations in the UGT1A1 gene promoter in Panamanians neonates with G6PD deficiency and its association with neonatal jaundice (NJ). We identified five different genotypes of TA repeats, in 17 neonates (42.5%) the normal variant TA6/TA6 and in the other 57.5% of the subjects TA7/TA7 (12.5%), TA6/TA7 (40%), TA6/TA8 (2.5%) and TA6/TA5 (2.5%). Additionally 75% of the 16 newborns that showed NJ had an abnormal variant in the promotersequence, although, there was no significant difference (P = 0.068). The risk of jaundice in neonates with TA7 variant was thrice higher in subjects than with other alleles (P = 0.093, CI 0.81-11.67). The TA7 allele frequency in this study (0.325) was consistent with the global frequency and similar to Caucasians. The results proved that there is no significant relationship between promoter polymorphism in UGT1A1 and NJ in G6PD deficient Panamanian newborns. Further studies with a greater number of subjects would determine the exact relationship between marked NJ and UGT1A promoter variations.
