Antimicrobial Property and Mode of Action of the Skin Peptides of the Sado Wrinkled Frog, Glandirana susurra, against Animal and Plant Pathogens. Antibiotics (Basel) 2020; 9:antibiotics9080457. [PMID: 32751229 PMCID: PMC7460468 DOI: 10.3390/antibiotics9080457] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 07/24/2020] [Accepted: 07/27/2020] [Indexed: 11/16/2022] Open
Abstract
The Sado wrinkled frog Glandirana susurra has recently been classified as a new frog species endemic to Sado Island, Japan. In this study, we cloned 12 cDNAs encoding the biosynthetic precursors for brevinin-2SSa–2SSd, esculentin-2SSa, ranatuerin-2SSa, brevinin-1SSa–1SSd, granuliberin-SSa, and bradykinin-SSa from the skin of G. susurra. Among these antimicrobial peptides, we focused on brevinin-2SSb, ranatuerin-2SSa, and granuliberin-SSa, using their synthetic replicates to examine their activities against different reference strains of pathogenic microorganisms that infect animals and plants. In broth microdilution assays, brevinin-2SSb displayed antimicrobial activities against animal pathogens Escherichia coli, Salmonella enterica, Pseudomonas aeruginosa, and Candida albicans and plant pathogens Xanthomonas oryzae pv. oryzae, Clavibacter michiganensis subsp. michiganensis, and Pyricularia oryzae. Ranatuerin-2SSa and granuliberin-SSa were active against C. albicans and C. michiganensis subsp. michiganensis, and granuliberin-SSa also was active against the other plant pathogenic microbes. Scanning electron microscopic observations demonstrated that brevinin-2SSb, ranatuerin-2SSa, and granuliberin-SSa induced morphological abnormalities on the cell surface in a wide range of the reference pathogens. To assess the bacterial-endotoxin-binding ability of the peptides, we developed an enzyme-linked endotoxin-binding assay system and demonstrated that brevinin-2SSb and ranatuerin-2SSa both exhibited high affinity to lipopolysaccharide and moderate affinity to lipoteichoic acid.

OctoPartenopin: Identification and Preliminary Characterization of a Novel Antimicrobial Peptide from the Suckers of Octopus vulgaris. Mar Drugs 2020; 18:md18080380.

Abstract
Microorganism resistance to conventional antibiotics represents one of the major global health concerns. This paper focuses on a peptide (OctoPartenopin) extracted from suckers of Octopus vulgaris; bioassay-guided chromatographic fractionation was used to identify this sequence, which holds significant antibacterial activity against Gram-positive and Gram-negative bacteria. OctoPartenopin is encrypted within the calponin sequence and was associated with the high levels of proteolytic activity already reported in octopus arm suckers. We synthesized the parent peptide and four analogues; all peptide were tested for their antibacterial and antibiofilm activities. Preliminary antibiofilm experiments showed that that one of the analogues had the best activity in both inhibition and eradication of biofilm of all three microorganisms tested. The occurrence of OctoPartenopin in arm suckers provided novel speculative information on animal behavior, as concerns maternal care of fertilized eggs. Our results highlight that suckers are a rich source of multifaceted peptides to develop alternative antimicrobial agents and food preservatives.

Abstract
Antimicrobial peptides (AMPs) were previously isolated from the skin of the Ryukyu brown frog Rana okinavana. However, this species has recently been reclassified as two species, i.e., Rana kobai and Rana ulma. As a result, it was determined that AMPs isolated from R. okinavana were in fact products of R. kobai, but not of R. ulma. In the present study, we collected skin samples from the species R. ulma and cloned twelve cDNAs encoding AMP precursors for the acyclic brevinin-1ULa--1ULf, the temporin-ULa-ULc, ranatuerin-2ULa, japonicin-1ULa, and a novel peptide using reverse-transcription polymerase chain reaction techniques. The deduced amino acid sequence of the novel peptide had a high similarity to those of Rana chensinensis chensinin-1CEa--1CEc, which were cloned by Zhao et al. ( 2011 ), but had a low similarity with R. chensinensis chensinin-1, which was cloned by Shang et al. ( 2009 ). To avoid confusion with these two different chensinin-1 families, we termed our peptide ulmin-1. Among these peptides, we focused on two peptides, brevinin-1ULf and ulmin-1ULa, and examined the antimicrobial and cytotoxic activity of their synthetic replicates. In broth microdilution assays, growth inhibitory activities against Staphylococcus aureus, Bacillus cereus, and Candida albicans were detected for brevinin-1ULf but not for ulmin-1ULa, whereas scanning electron microscopic observations revealed that both peptides induce morphological abnormalities in these microbes. In addition, binding activity of ulmin-1ULa to the bacterial cell wall component lipoteichoic acid was higher than that of brevinin-1ULf. In contrast, hemolytic and cytotoxic activities of brevinin-1ULf were stronger than those of ulmin-1ULa.

Abstract
Host defense peptides (HDPs) are currently major focal points of medical research as infectious microbes are gaining resistance to existing drugs. They are effective against multi-drug resistant pathogens due to their unique primary target, biological membranes, and their peculiar mode of action. Even though HDPs from 60 Asian frog species belonging to 15 genera have been characterized, research into these peptides is at a very early stage. The purpose of this review is to showcase the status of peptide research in Asia. Here we provide a summary of HDPs from Asian frogs.

Abstract
Amphibian skin secretion has great potential for drug discovery and contributes hundreds of bioactive peptides including bradykinin-related peptides (BRPs). More than 50 BRPs have been reported in the last two decades arising from the skin secretion of amphibian species. They belong to the families Ascaphidae (1 species), Bombinatoridae (3 species), Hylidae (9 speices) and Ranidae (25 species). This paper presents the diversity of structural characteristics of BRPs with N-terminal, C-terminal extension and amino acid substitution. The further comparison of cDNA-encoded prepropeptides between the different species and families demonstrated that there are various forms of kininogen precursors to release BRPs and they constitute important evidence in amphibian evolution. The pharmacological activities of isolated BRPs exhibited unclear structure–function relationships, and therefore the scope for drug discovery and development is limited. However, their diversity shows new insights into biotechnological applications and, as a result, comprehensive and systematic studies of the physiological and pharmacological activities of BRPs from amphibian skin secretion are needed in the future.

Abstract
Amphibians exhibit various, characteristic adaptations related to their "incomplete" shift from the aquatic to the terrestrial habitat. In particular, the integument was subject to a number of specialized modifications during the evolution of these animals. In this review, we place special emphasis on endogenous host-defence skin peptides from the cuteanous granular glands anuran amphibians (frogs and toads). The overview on the two broad groups of neuroactive and antimicrobial peptides (AMPs) goes beyond a simple itemization in that we provide a new perspective into the evolution and function of anuran AMPs. Briefly, these cationic, amphipathic and α-helical peptides are traditionally viewed as being part of the innate immune system, protecting the moist skin against invading microorganisms through their cytolytic action. However, the complete record of anuran species investigated to date suggests that AMPs are distributed sporadically (i.e., non-universally) across Anura. Together with the intriguing observation that virtually all anurans known to produce neuropeptides in their granular glands also co-secrete cytolytic peptides, we call the traditional role for AMPs as being purely antimicrobial into question and present an alternative scenario. We hypothesize AMPs to assist neuroactive peptides in their antipredator role through their cytolytic action increasing the delivery of the latter to the endocrine and nervous system of the predator. Thus, AMPs are more accurately viewed as cytolysins and their contribution to the immune system is better regarded as an accessory benefit.

Abstract
Antimicrobial peptides are the backbone of first-line defense against various microorganisms in the animal kingdom. Thus, not surprisingly, they are gaining attention in the science and medical fields as a rich repository of new pro-drugs. Below, we focus our attention on the Brevinin family of anuran peptides. While most of them show strong antibacterial activities, some, e.g. Brevinin-2R, appear to be promising anticancer molecules, exhibiting better a therapeutic window than widely-use anticancer drugs like doxorubicin. We briefly introduce the field, followed by highlighting the promising therapeutic properties of Brevinins. Next, we provide information about the cloning and phylogenetic aspects of Brevinin genes. In the final paragraphs of this chapter, we discuss possible large-scale production methods of Brevinins, giving examples of some systems that are already in use. Towards the end, we discuss various means of modification of biologic properties of Brevinins, either by chemical modifications or by amino acid substitution and sequence rearrangements. In this context, also other unique properties of Brevinins are briefly mentioned. Finally, we discuss the future of the Brevinin field, particularly highlighting yet to be answered biologic questions, like for example presumed anti-viral and antitumor activities of Brevinin family members.

Abstract
As one of large amphibian group, there are a total of 45 species of Amolops in the world. However, the antimicrobial peptides (AMPs) existing in this genus has not been extensively studied. In this study, cDNAs encoding five novel AMP precursors were cloned by screening the skin-derived cDNA library of Amolops ricketti, a frog species that exists in southern and western parts of China. Protein sequence analysis led to the identification of five deduced peptides, three belonging to the brevinin-1 family and two belonging to the brevinin-2 family of amphibian AMPs. Thus, they were named as brevinin-1RTa (FLPLLAGVVANFLPQIICKIARKC), brevinin-1RTb (FLGSLLGLVGKVVPTLFCKISKKC), brevinin-1RTc (FLGSLLGLVGKIVPTLICKISKKC), brevinin-2RTa (GLMSTLKDFGKTAAKEIAQSLLSTASCKLAKTC), and brevinin-2RTb (GILDTLKEFGKTAAKGIAQSLLSTASCKLAKTC), respectively. The purification of brevinin-1RTa, brevinin-1RTb, and brevinin-2RTb was carried out by RP-HPLC, and confirmed by the LC-MS/MS-based proteomics approach. All of the peptides displayed different antimicrobial potency against a variety of microorganisms. In addition, brevinin-2RTa and brevinin-2RTb were found to have relatively low hemolytic activity (>400μg/ml) against mammalian red blood cells in vitro, which could potentially be as candidates for developing novel anti-infection agents.

Abstract
Extensive studies on bradykinin-related peptides (BRPs) generated from plasma kininogens in representative species of various vertebrate taxa, have confirmed that many amphibian skin BRPs reflect those present in putative vertebrate predators. For example, the (Val(1), Thr(6))-bradykinin, present in the defensive skin secretions of many ranids and phyllomedusines, can be generated from plasma kininogens in colubrid snakes-common predators of these frogs. Here, we report the presence of (Arg(0), Trp(5), Leu(8))-bradykinin in the skin secretion of the European edible frog, Pelophylax kl. esculentus, and have found it to be encoded in single copy by a kininogen with an open-reading frame of 68 amino acid residues. This peptide is the archetypal bony fish bradykinin that has been generated from plasma kininogens of the bowfin (Amia calva), the long-nosed gar (Lepisosteus oseus) and the rainbow trout (Onchorhynchus mykiss). More recently, this peptide has been shown to be encoded within cloned kininogens of the Atlantic cod (Gadus morhua) spotted wolf-fish (Anarichas minor), zebrafish (Danio rerio), pufferfish (Tetraodon nigroviridis) and Northern pike (Esox lucius). The latter species is regarded as a major predator of P. kl. esculentus. Synthetic (Arg(0), Trp(5), Leu(8))-bradykinin was previously reported as having multiphasic effects on arterial blood pressure in conscious trout and here we have demonstrated that it can antagonize the relaxation in rat arterial smooth muscle induced by canonical mammalian bradykinin. The discovery of (Arg(0), Trp(5), Leu(8))-bradykinin in the defensive skin secretion of this amphibian completes the spectrum of vertebrate taxon-specific BRPs identified from this source.

Abstract
The Harderian gland is an orbital gland found in many tetrapod species that possess a nictitating membrane. While the main role of the Harderian gland is lubrication of the eyeballs, numerous other functions are attributed to this gland. In amphibians, mast cells have been detected in the Harderian gland, suggesting that the gland is involved in the host's system of innate immunity defending against microbial invasions. Using reverse-transcription polymerase chain reaction, we cloned from the bullfrog Harderian gland total RNA preparations, cDNAs encoding biosynthetic precursors for the antimicrobial peptides temporin-CBa (FLPIASLLGKYL-NH2), previously isolated from an extract of bullfrog skin, and chensirin-2CBa (IIPLPLGYFAKKP) that contained the amino acid substitution Thr13-->Pro compared with chensirin-2 from the Chinese brown frog, Rana chensinensis. By means of in situ hybridization using digoxigenin-labeled cRNA probes for preprotemporin-CBa and preprochensirin-2CBa, we have demonstrated for the first time in an amphibian the presence of mRNAs encoding these two precursors in the cytoplasm of the glandular cells in the bullfrog Harderian gland.

Abstract
Bradykinin-related peptides (BRPs) constitute one of the most studied groups of bioactive peptides in amphibian skin secretions. The present study describes the successful isolation of a novel BRP (hylaranakinin TE) from the skin secretion of the Indian bronzed frog Hylarana temporalis. The deduced open reading frame consisted of 115 amino acid residues with a putative signal peptide of 22 amino acid residues, followed by a spacer region and mature peptide regions that encode for two BRPs: a canonical bradykinin R-9-R with a C-terminal extension of FVPASSL and Thr6-BK. The Thr6-BK reported in the present study had an unusual FP-insertion in the N-terminal part and ended in FAPEII, which is very different from the IAPAIV sequence reported in other ranid frogs. Unlike the mammalian bradykinin and its precursor, amphibian BRPs and their precursors are extremely variable, as evident from the present study. This forms the first report of BRPs from Hylarana temporalis, endemic to India and Sri Lanka.
