Functional analysis of acyl-CoA dehydrogenases and their application to C22 steroid production.
Article in Applied microbiology and biotechnology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Acyl-CoA dehydrogenase (ChsE) is involved in the steroid side-chain degradation process. However, their function in vivo remains unclear. In this study, three ChsE, ChsE1-ChsE2, ChsE3, and ChsE4-ChsE5, were identified in Mycolicibacterium neoaurum, and their functions in vivo are studied and compared with those from Mycobacterium tuberculosis in vitro. By gene knockout, complementation, and the bioconversion of phytosterols, the function of ChsE was elucidated that ChsE4-ChsE5 could utilize C27, C24, and C22 steroids in vivo. ChsE3 could utilize C27 and C24 steroids in vivo. ChsE1-ChsE2 could utilize C27, C24, and C22 steroids in vivo. What is more, the production strain of a C22 steroid, 3-oxo-4,17-pregadiene-20-carboxylic acid methyl ester (PDCE), is constructed with ChsE overexpression. This study improved the understanding of the steroid bioconversion pathway and proposed a method of the production of a new C22 steroid. KEY POINTS: • Three ChsE paralogs from M. neoaurum are identified and studied. • The function of ChsE is overlapped in vivo. • A C22 steroid (PDCE) producer was constructed with ChsE overexpression.
