Abstract
Tuberculosis (TB) is an infectious airborne disease caused by Mycobacterium tuberculosis. Since the 1990 s, many countries have made significant progress in reducing the incidence of TB and associated mortality by improving health services and strengthening surveillance systems. Nevertheless, due to the emergence of multidrug-resistant TB (MDR-TB), alongside extensively drug-resistant TB (XDR-TB) and TB-HIV co-infection, TB remains one of the lead causes of death arising from infectious disease worldwide, especially in developing countries and disadvantaged populations. Marine natural products (MNPs) have received a large amount of attention in recent years as a source of pharmaceutical constituents and lead compounds, and are expected to offer significant resources and potential in the fields of drug development and biotechnology in the years to come. This review summarizes 169 marine natural products and their synthetic derivatives displaying anti-TB activity from 2013 to the present, including their structures, sources and functions. Partial synthetic information and structure-activity relationships (SARs) are also included.

Abstract
Polyamines are bioactive amines that play a variety of roles, such as promoting cell proliferation and protein synthesis, and the intestinal lumen contains up to several mM polyamines derived from the gut microbiota. In the present study, we conducted genetic and biochemical analyses of the polyamine biosynthetic enzyme N-carbamoylputrescine amidohydrolase (NCPAH) that converts N-carbamoylputrescine to putrescine, a precursor of spermidine in Bacteroides thetaiotaomicron, which is one of the most dominant species in the human gut microbiota. First, ncpah gene deletion and complemented strains were generated, and the intracellular polyamines of these strains cultured in a polyamine-free minimal medium were analyzed using high-performance liquid chromatography. The results showed that spermidine detected in the parental and complemented strains was depleted in the gene deletion strain. Next, purified NCPAH-(His)6 was analyzed for enzymatic activity and found to be capable of converting N-carbamoylputrescine to putrescine, with a Michaelis constant (Km) and turnover number (kcat) of 730 µM and 0.8 s-1, respectively. Furthermore, the NCPAH activity was strongly (>80%) inhibited by agmatine and spermidine, and moderately (≈50%) inhibited by putrescine. This feedback inhibition regulates the reaction catalyzed by NCPAH and may play a role in intracellular polyamine homeostasis in B. thetaiotaomicron.

Abstract
The bacterial genus Tenacibaculum has been associated with various ecological roles in marine environments. Members of this genus can act, for example, as pathogens, predators, or episymbionts. However, natural products produced by these bacteria are still unknown. In the present work, we investigated a Tenacibaculum strain for the production of antimicrobial metabolites. Six new phenethylamine (PEA)-containing alkaloids, discolins A and B (1 and 2), dispyridine (3), dispyrrolopyridine A and B (4 and 5), and dispyrrole (6), were isolated from media produced by the predatory bacterium Tenacibaculum discolor sv11. Chemical structures were elucidated by analysis of spectroscopic data. Alkaloids 4 and 5 exhibited strong activity against Gram-positive Bacillus subtilis DSM10, Mycobacterium smegmatis ATCC607, Listeria monocytogenes DSM20600, and Staphylococcus aureus ATCC25923, with minimum inhibitory concentration (MIC) values ranging from 0.5 to 4 μg/mL, and moderate activity against Candida albicans FH2173 and Aspergillus flavus ATCC9170. Compound 6 displayed moderate antibacterial activities against Gram-positive bacteria. Dispyrrolopyridine A (4) was active against efflux pump deficient Escherichia coli ATCC25922 ΔtolC, with an MIC value of 8 μg/mL, as well as against Caenorhabditis elegans N2 with an MIC value of 32 μg/mL. Other compounds were inactive against these microorganisms. The biosynthetic route toward discolins A and B (1 and 2) was investigated using in vivo and in vitro experiments. It comprises an enzymatic decarboxylation of phenylalanine to PEA catalyzed by DisA, followed by a nonenzymatic condensation to form the central imidazolium ring. This spontaneous formation of the imidazolium core was verified by means of a synthetic one-pot reaction using the respective building blocks. Six additional strains belonging to three Tenacibaculum species were able to produce discolins, and several DisA analogues were identified in various marine flavobacterial genera, suggesting the widespread presence of PEA-derived compounds in marine ecosystems.

Abstract
BACKGROUND Male fertility impaired by exogenous toxins is a serious worldwide issue threatening the health of the new-born and causing infertility. However, the metabolic connection between toxic exposures and testicular dysfunction remains unclear. RESULTS In the present study, the metabolic disorder of testicular dysfunction was investigated using triptolide-induced testicular injury in mice. We found that triptolide induced spermine deficiency resulting from disruption of polyamine biosynthesis and uptake in testis, and perturbation of the gut microbiota. Supplementation with exogenous spermine reversed triptolide-induced testicular dysfunction through increasing the expression of genes related to early and late spermatogenic events, as well as increasing the reduced number of offspring. Loss of gut microbiota by antibiotic treatment resulted in depletion of spermine levels in the intestine and potentiation of testicular injury. Testicular dysfunction in triptolide-treated mice was reversed by gut microbial transplantation from untreated mice and supplementation with polyamine-producing Parabacteroides distasonis. The protective effect of spermine during testicular injury was largely dependent on upregulation of heat shock protein 70s (HSP70s) both in vivo and in vitro. CONCLUSIONS The present study linked alterations in the gut microbiota to testicular dysfunction through disruption of polyamine metabolism. The diversity and dynamics of the gut microbiota may be considered as a therapeutic option to prevent male infertility. Video Abstract.

Abstract
Polyamines are positively charged small molecules ubiquitously existing in all living organisms, and they are considered as one kind of the most ancient cellular components. The most common polyamines are spermidine, spermine, and their precursor putrescine generated from ornithine. Polyamines play critical roles in cells by stabilizing chromatin structure, regulating DNA replication, modulating gene expression, etc., and they also affect the structure and function of proteins. A few studies have investigated the impact of polyamines on protein structure and function previously, but no reports have focused on a protein-based biological module with a dedicated function. In this report, we investigated the impact of polyamines (putrescine, spermidine, and spermine) on the cyanobacterial KaiABC circadian oscillator. Using an established in vitro reconstitution system, we noticed that polyamines could disrupt the robustness of the KaiABC oscillator by inducing the denaturation of the Kai proteins (KaiA, KaiB, and KaiC). Further experiments showed that the denaturation was likely due to the induced change of the thermal stability of the clock proteins. Our study revealed an intriguing role of polyamines as a component in complex cellular environments and would be of great importance for elucidating the biological function of polyamines in future.

Abstract
Polyamine concentrations in the intestine are regulated by their biosynthesis by hundreds of gut microbial species and these polyamines are involved in host health and disease. However, polyamine biosynthesis has not been sufficiently analyzed in major members of the human gut microbiota, possibly owing to a lack of gene manipulation systems. In this study, we successfully performed markerless gene deletion in Bacteroides dorei, one of the major members of the human gut microbiota. The combination of a thymidine kinase gene (tdk) deletion mutant and a counter-selection marker tdk, which has been applied in other Bacteroides species, was used for the markerless gene deletion. Deletion of tdk in B. dorei caused 5-fluoro-2΄-deoxyuridine resistance, suggesting the utility of B. dorei Δtdk as the host for future markerless gene deletions. Compared to parental strains, an arginine decarboxylase gene (speA) deletion mutant generated in this system showed a severe growth defect and decreased concentration of spermidine in the cells and culture supernatant. Collectively, our results indicate the accessibility of gene deletion and the important role of speA in polyamine biosynthesis in B. dorei.

Abstract
Recent studies have reported that polyamines in the colonic lumen might affect animal health and these polyamines are thought to be produced by gut bacteria. In the present study, we measured the concentrations of three polyamines (putrescine, spermidine, and spermine) in cells and culture supernatants of 32 dominant human gut bacterial species in their growing and stationary phases. Combining polyamine concentration analysis in culture supernatant and cells with available genomic information showed that novel polyamine biosynthetic proteins and transporters were present in dominant human gut bacteria. Based on these findings, we suggested strategies for optimizing polyamine concentrations in the human colonic lumen via regulation of genes responsible for polyamine biosynthesis and transport in the dominant human gut bacteria.

Abstract
Recent studies have indicated that polyamines produced by gut microbes significantly influence host health; however, little is known about the microbial polyamine biosynthetic pathway except for that in Escherichia coli, a minor component of the gastrointestinal microbiota. Here, we investigated the polyamine biosynthetic ability of Bacteroides thetaiotaomicron, a predominant gastrointestinal bacterial species in humans. High-performance liquid chromatography analysis revealed that B. thetaiotaomicron cultured in polyamine-free minimal medium accumulated spermidine intracellularly at least during the mid-log and stationary phases. Deletion of the gene encoding a putative carboxyspermidine decarboxylase (casdc), which converts carboxyspermidine to spermidine, resulted in the depletion of spermidine and loss of decarboxylase activity in B. thetaiotaomicron. The Δcasdc strain also showed growth defects in polyamine-free growth medium. The complemented Δcasdc strain restored the spermidine biosynthetic ability, decarboxylase activity, and growth. These results indicate that carboxyspermidine decarboxylase is essential for synthesizing spermidine in B. thetaiotaomicron and contributes to the growth of this species.

Abstract
Two black-pigmented, anaerobic bacterial strains, designated LMM 40T and LMM 41, were isolated from the bovine post-partum endometrium of two Holstein cows. The 16S rRNA gene sequences of the two strains were identical and showed the highest similarity to the 16S rRNA gene sequence of the type strain of
Porphyromonas crevioricanis
(90.2 %) but only 85.1 % 16S rRNA gene sequence similarity to the type strain of the type species of the genus
Porphyromonas
,
Porphyromonas asaccharolytica
. The major fatty acid profiles of the two strains were similar to those of species of the genus
Porphyromonas
, containing iso-C15 : 0 as the major component and moderate amounts of anteiso-C15 : 0, iso-C13 : 0, C15 : 0 and C16 : 0. Hydroxylated fatty acids, such as iso-C14 : 0 3-OH, iso-C16 : 0 3-OH and iso-C17 : 0 3-OH, were also detected. The quinone profiles were dominated by the menaquinones MK-8 and MK-9, while spermidine was the major polyamine. The polar lipid profiles contained major amounts of phosphatidylethanolamine, an unidentified phospholipid, an unidentified aminophospholipid and two unidentified lipids and minor amounts of phosphatidylglycerol, an unidentified aminolipid, a second unidentified aminophospholipid and an unidentified glycolipid. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The genomic DNA G+C contents of LMM 40T and LMM 41 were 40.7 and 41.3 mol%, respectively. Based on a polyphasic approach, including phylogenetic analysis, physiological and biochemical tests as well as metabolic fingerprinting, it is proposed that the two strains are members of a novel genus and species, for which the name Falsiporphyromonas endometrii gen. nov., sp. nov. is proposed. The type strain of Falsiporphyromonas endometrii is LMM 40T ( = DSM 27210T = CCUG 64267T). An emended description of the genus
Porphyromonas
is also presented.

Abstract
A pinkish-pigmented, Gram-stain-negative, rod-shaped, non-spore-forming bacterium, strain E92(T), was isolated from the skin of the medical leech Hirudo medicinalis, on R2A agar. 16S rRNA gene sequence analysis of strain E92(T) showed a relatively low 16S rRNA gene sequence similarity (93.0-93.5 %) to representatives of the genus Arcicella and 91.5-92.0 % to members of the genus Flectobacillus. The polar lipid profile was composed of the major compounds phosphatidylethanolamine, an unidentified aminophospholipid, an unidentified aminolipid and an unidentified polar lipid; glycolipids were not detected. The major quinone was menquinone MK-7, and the major compound in the polyamine pattern was spermidine. The predominant fatty acids were C(16 : 1)ω5c and C(16 : 1)ω7c and/or iso-C(15 : 0) 2-OH (detected as summed feature 3). The isolate did not contain C(14 : 0) or the hydroxyl fatty acid iso-C(17 : 0) 3-OH found in all representatives of the genera Arcicella and Flectobacillus, but did produce C(18 : 1)ω7c and 11-methyl C(18 : 1)ω7c which are not found in these two genera. The DNA G+C content of strain E92(T) was 64.4 mol%. The unique 16S rRNA gene sequence, and specific chemotaxonomic and physiological data revealed that strain E92(T) represents a new genus in the family Cytophagaceae for which we propose the name Pseudarcicella hirudinis gen. nov., sp. nov., with the type strain of the type species as E92(T) (= LMG 26720(T) = CCM 7988(T)).

Abstract
Polyamines are small flexible organic polycations found in almost all cells. They likely existed in the last universal common ancestor of all extant life, and yet relatively little is understood about their biological function, especially in bacteria and archaea. Unlike eukaryotes, where the predominant polyamine is spermidine, bacteria may contain instead an alternative polyamine, sym-homospermidine. We demonstrate that homospermidine synthase (HSS) has evolved vertically, primarily in the alpha-Proteobacteria, but enzymatically active, diverse HSS orthologues have spread by horizontal gene transfer to other bacteria, bacteriophage, archaea, eukaryotes, and viruses. By expressing diverse HSS orthologues in Escherichia coli, we demonstrate in vivo the production of co-products diaminopropane and N(1)-aminobutylcadaverine, in addition to sym-homospermidine. We show that sym-homospermidine is required for normal growth of the alpha-proteobacterium Rhizobium leguminosarum. However, sym-homospermidine can be replaced, for growth restoration, by the structural analogues spermidine and sym-norspermidine, suggesting that the symmetrical or unsymmetrical form and carbon backbone length are not critical for polyamine function in growth. We found that the HSS enzyme evolved from the alternative spermidine biosynthetic pathway enzyme carboxyspermidine dehydrogenase. The structure of HSS is related to lysine metabolic enzymes, and HSS and carboxyspermidine dehydrogenase evolved from the aspartate family of pathways. Finally, we show that other bacterial phyla such as Cyanobacteria and some alpha-Proteobacteria synthesize sym-homospermidine by an HSS-independent pathway, very probably based on deoxyhypusine synthase orthologues, similar to the alternative homospermidine synthase found in some plants. Thus, bacteria can contain alternative biosynthetic pathways for both spermidine and sym-norspermidine and distinct alternative pathways for sym-homospermidine.
