Description of Streptomyces naphthomycinicus sp. nov., an endophytic actinobacterium producing naphthomycin A and its genome insight for discovering bioactive compounds. Front Microbiol 2024; 15:1353511. [PMID: 38694805 PMCID: PMC11061393 DOI: 10.3389/fmicb.2024.1353511] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 04/01/2024] [Indexed: 05/04/2024] Open
Abstract
Endophytic actinobacteria are a group of bacteria living inside plant tissue without harmful effects, and benefit the host plant. Many can inhibit plant pathogens and promote plant growth. This study aimed to identify a strain of Streptomyces as a novel species and study its antibiotics production. An endophytic actinobacterium, strain TML10T was isolated from a surface-sterilized leaf of a Thai medicinal plant (Terminalia mucronata Craib and Hutch). As a result of a polyphasic taxonomy study, strain TML10T was identified as a member of the genus Streptomyces. Strain TML10T was an aerobic actinobacterium with well-developed substrate mycelia with loop spore chains and spiny surface. Chemotaxonomic data, including cell wall components, major menaquinones, and major fatty acids, confirmed the affiliation of strain TML10T to the genus Streptomyces. The results of the phylogenetic analysis, including physiological and biochemical studies in combination with a genome comparison study, allowed the genotypic and phenotypic differentiation of strain TML10T and the closest related type strains. The digital DNA-DNA hybridization (dDDH), Average nucleotide identity Blast (ANIb), and ANIMummer (ANIm) values between strain TML10T and the closest type strain, Streptomyces musisoli CH5-8T were 38.8%, 88.5%, and 90.8%, respectively. The name proposed for the new species is Streptomyces naphthomycinicus sp. nov. (TML10T = TBRC 15050T = NRRL B-65638T). Strain TML10T was further studied for liquid and solid-state fermentation of antibiotic production. Solid-state fermentation with cooked rice provided the best conditions for antibiotic production against methicillin-resistant Staphylococcus aureus. The elucidation of the chemical structures from this strain revealed a known antimicrobial agent, naphthomycin A. Mining the genome data of strain TML10T suggested its potential as a producer of antbiotics and other valuable compounds such as ε-Poly-L-lysine (ε-PL) and arginine deiminase. Strain TML10T contains the arcA gene encoding arginine deiminase and could degrade arginine in vitro.

Abstract
BACKGROUND Colorectal cancer which is related to genetic and environmental risk factors, is among the most prevalent life-threatening cancers. Although several pathogenic bacteria are associated with colorectal cancer etiology, some others are considered as highly selective therapeutic agents in colorectal cancer. Nowadays, researchers are concentrating on bacteriotherapy as a novel effective therapeutic method with fewer or no side effects to pay the way of cancer therapy. The introduction of advanced and successful strategies in bacterial colorectal cancer therapy could be useful to identify new promising treatment strategies for colorectal cancer patients. MAIN TEXT In this article, we scrutinized the beneficial effects of bacterial therapy in colorectal cancer amelioration focusing on different strategies to use a complete bacterial cell or bacterial-related biotherapeutics including toxins, bacteriocins, and other bacterial peptides and proteins. In addition, the utilization of bacteria as carriers for gene delivery or other known active ingredients in colorectal cancer therapy are reviewed and ultimately, the molecular mechanisms targeted by the bacterial treatment in the colorectal cancer tumors are detailed. CONCLUSIONS Application of the bacterial instrument in cancer treatment is on its way through becoming a promising method of colorectal cancer targeted therapy with numerous successful studies and may someday be a practical strategy for cancer treatment, particularly colorectal cancer.

[PMID: 32373418 DOI: 10.1007/s13205-020-02212-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2020] [Accepted: 04/16/2020] [Indexed: 01/04/2023] Open
Abstract
In the present study, arginine deaminase (ADI) was purified from Pseudomonas aeruginosa PS2 which showed relative molecular mass of 70 ± 3 kDa on native-PAGE and 36 ± 0.5 kDa on SDS-PAGE. Purified ADI exhibited optimum activity at pH 6.5 and temperature 40 ºC. Metal ions, K+ and Mg2+ had positive, while Mn2+, Cr2+, Co2+, Fe3+, Ni2+, Cu2+, Cd2+ and Hg2+ had negative effects on catalytic activity of ADI. Purified enzyme showed high substrate specificity towards natural substrate L-arginine and did not hydrolyse its structural analogues. In-vitro serum half-life of purified ADI was 40 h, whereas proteolytic half-life was 28, 27, and 32 min against trypsin, elastase-I and proteinase-K, respectively. Anticancer activity of ADI has been evaluated against panel of human cancer cell lines (LS-180, HCT-116, MCF-7, BT-549, T47D, HL-60, MOLT-4, K-562, and PC-3) but lowest IC50 1.2 IU ml-1 was recorded with MCF-7 cells. Colony forming assay, wound-healing migration assay, phase contrast microscopy, DAPI staining, cell cycle analysis and DNA laddering assay revealed that ADI treatment induced apoptotic cell death in dose dependent manner. Increased level of MMP loss, ROS generation and decreased level of SOD, CAT, GPx and GSH displayed ADI treatment induced mitochondrial dysfunctioning. Furthermore, purified ADI had no substantial toxicity against human normal cell lines and blood erythrocytes. These findings suggesting that purified ADI could be developed as an anticancer agent but more in depth studies are warranted.

Abstract
Background:Arginine deiminase of Mycoplasma hominis, an arginine catabolizing enzyme, is currently in clinical trial for the treatment of arginine auxotrophic cancers. However, some drawbacks such as instability and antigenicity have limited its application as a protein drug. Arginine Deiminase (ADI) belongs to the guanidino-group modifying enzyme superfamily. Despite differences in the primary amino acid sequences of various members of this superfamily, the folding and secondary structures are conserved in all members. Despite structural similarities, ADIs in various species have different levels of catalytic activity and physicochemical properties due to the differences in their primary amino acid sequences. Therefore, investigating and comparing sequences between different ADI producing bacterial strains could be helpful in the rational engineering of ADI.Objective:In the current research, we used an in-silico approach to characterize and classify the available reviewed protein sequences of ADI.Results:102 ADI sequences from SwissProt database were extracted. Subsequently, based on clustering analyses, the sequence sets were divided into five distinct groups. Different physicochemical properties, solubility, and antigenicity of the enzymes were determined. Some ADI sequences were introduced as well-suited candidates for protein engineering; Lactobacillus fermentum ADI for low pI value, Mycobacterium avium ADI for high aliphatic index, Bacillus licheniformis ADI for low GRAVY index, Bradyrhizobium diazoefficiens ADI for low antigenicity and high stability index, and among Mycoplasma ADIs, Mycoplasma arthritidis ADI for high stability and aliphatic index, and Mycoplasma capricolum for low antigenicity.

Abstract
BACKGROUND Arginine deiminase (ADI), an arginine catabolizing enzyme, is considered as an anti-tumor agent for the treatment of arginine auxotrophic cancers. However, some obstacles limit its clinical applications. OBJECTIVE This review will summarize the clinical applications of ADI, from a brief history to its limitations, and will discuss the different ways to deal with the clinical limitations. METHOD The structure analysis, cloning, expression, protein engineering and applications of arginine deiminase enzyme have been explained in this review. CONCLUSION Recent patents on ADI are related to ADI engineering to increase its efficacy for clinical application. The intracellular delivery of ADI and combination therapy seem to be the future strategies in the treatment of arginine auxotrophic cancers. Applying ADIs with optimum features from different sources and or ADI engineering, are promising strategies to improve the clinical application of ADI.
