Significance of both alkB and P450 alkane-degrading systems in Tsukamurella tyrosinosolvens: proteomic evidence. Appl Microbiol Biotechnol 2022; 106:3153-3171. [PMID: 35396956 DOI: 10.1007/s00253-022-11906-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 03/21/2022] [Accepted: 03/29/2022] [Indexed: 11/02/2022]
Abstract
The Tsukamurella tyrosinosolvens PS2 strain was isolated from hydrocarbons-contaminated petrochemical sludge as a long chain alkane-utilizing bacteria. Complete genome analysis showed the presence of two alkane oxidation systems: alkane 1-monooxygenase (alkB) and cytochrome P450 monooxygenase (P450) genes with established high homology to the well-known alkane-degrading actinobacteria. According to the comparative genome analysis, both systems have a wide distribution among environmental and clinical isolates of the genus Tsukamurella and other members of Actinobacteria. We compared the expression of different proteins during the growth of Tsukamurella on sucrose and on hexadecane. Both alkane monooxygenases were upregulated on hexadecane: AlkB-up to 2.5 times, P450-up to 276 times. All proteins of the hexadecane oxidation pathway to acetyl-CoA were also upregulated. Accompanying proteins for alkane degradation involved in biosurfactant synthesis and transport of organic and inorganic molecules were increased. The change in the carbon source affected the pathways for the regulation of translation and transcription. The proteomic profile showed that hexadecane is an adverse factor causing activation of general and universal stress proteins as well as shock and resistance proteins. Differently expressed proteins of Tsukamurella tyrosinosolvens PS2 shed light on the alkane degradation in other members of Actinobacteria class. KEY POINTS: • alkB and P450 systems have a wide distribution among the genus Tsukamurella. • alkB and P450 systems have coexpression with the predominant role of P450 protein. • Hexadecane causes significant changes in bacterial proteome.

Label-free proteomic dissection on dptP-deletion mutant uncovers dptP involvement in strain growth and daptomycin tolerance of Streptomyces roseosporus. Microb Biotechnol 2020; 14:708-725.

Abstract
Daptomycin (DAP) is a novel microbial lipopeptide antibiotic synthesized by the DAP biosynthetic gene cluster dpt of Streptomyces roseosporus (S. roseosporus). DptP gene locates upstream of dpt and confers DAP resistance to Streptomyces ambofaciens (S. ambofaciens). So far, the biological functions of dptP gene for S. roseosporus growth are still completely uncovered. We performed label‐free quantification proteomic dissections with loss‐ and gain‐of‐function experiments to decipher dptP‐involved functions. Deletion of dptP gene activated energy metabolism and metabolism of secondary metabolites pathways and enhanced the transcription levels and protein abundance of key members of the dpt cluster. Whereas dptP deletion inhibited transport/signal transduction and drug resistance pathways and protein abundance of cell division‐relative proteins, subsequently decreased mycelia cell growth rate. S. roseosporus strain with dptP deletion was more sensitive to DAP treatment compared to the wild type. In contrast, overexpression of dptP gene decreased transcription levels of DAP biosynthetic genes and enhanced growth rate of Streptomcyes strain upon elevated culture temperature and DAP supplementation. Taken together, dptP gene contributes to Streptomcyes primary growth under elevated temperature and DAP treatment, whereas it plays negative roles on metabolism of secondary metabolites and transcription of DAP biosynthetic genes.
