Characterization of the cystargolide biosynthetic gene cluster and functional analysis of the methyltransferase CysG. J Biol Chem 2024; 300:105507. [PMID: 38029966 PMCID: PMC10776993 DOI: 10.1016/j.jbc.2023.105507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 11/17/2023] [Accepted: 11/21/2023] [Indexed: 12/01/2023] Open
Abstract
Cystargolides are natural products originally isolated from Kitasatospora cystarginea NRRL B16505 as inhibitors of the proteasome. They are composed of a dipeptide backbone linked to a β-lactone warhead. Recently, we identified the cystargolide biosynthetic gene cluster, but systematic genetic analyses had not been carried out because of the lack of a heterologous expression system. Here, we report the discovery of a homologous cystargolide biosynthetic pathway in Streptomyces durhamensis NRRL-B3309 by genome mining. The gene cluster was cloned via transformation-associated recombination and heterologously expressed in Streptomyces coelicolor M512. We demonstrate that it contains all genes necessary for the production of cystargolide A and B. Single gene deletion experiments reveal that only five of the eight genes from the initially proposed gene cluster are essential for cystargolide synthesis. Additional insights into the cystargolide pathway could be obtained from in vitro assays with CysG and chemical complementation of the respective gene knockout. This could be further supported by the in vitro investigation of the CysG homolog BelI from the belactosin biosynthetic gene cluster. Thereby, we confirm that CysG and BelI catalyze a cryptic SAM-dependent transfer of a methyl group that is critical for the construction of the cystargolide and belactosin β-lactone warheads.

Abstract
Herein, we report a strategy for the total synthesis of a structurally unique fungal glycolipid fusaroside. The first total synthesis of the proposed structure involved construction of the complex, branched lipid chain having a variety of alkenes with E stereochemistry and attachment of the masked α,β-unsaturated β-keto acid at the O-4 position of trehalose as key steps. We propose a revision in the structure of fusaroside, particularly the position of olefins in the lipid chain.

Abstract
An aliphatic alcohol 12-hydroxyhentriacontane has been synthesised for the first time. The synthetic route of this naturally occurring alcohol adopts the techniques of microwave and ultrasonic irradiation. The synthetic approach provided enough material to corroborate the structure of the target molecule which had been isolated from leaves of Ziziphus mauritiana and exhibits excellent anti-inflammatory, antibacterial and antimicrobial properties.

Abstract
A variety of trehalose glycolipids have been isolated from natural sources, and several of these glycolipids exhibit important biological properties. These molecules also represent challenging synthetic targets due to their highly amphiphilic character, their large number of functional groups and additional chiral centres. This review highlights some of the recent advances made in the synthesis of trehalose glycolipids, and their associated biological activities.
