A critical factor behind this system may be represented by the availability of a specific promoter driving Cre expression in the cell subset of interest. Split-Cre recombinase system represents an evolution that circumvents this limitation using split N- and C-terminal domains of Cre recombinase placed under the control of two distinct promoters defining an intersectional domain where functional complementation of Cre protein fragments is obtained. This system is a valuable tool for controlling Cre recombinase activity in a spatially and temporally defined manner based on the assumption that neither N- or C-terminal Cre fragments alone have recombinase activity. However, residual recombinase activity of one of the two fragments can occur leading to confounding experimental results. In this work, we delve into characterizing functional activity of different N-terminal deleted codon-optimized Cre (iCre) isoforms to refine Split-Cre-based technologies, aiming to avoid uncontrolled recombinase events. Given the presence of several methionine residues in the amino acidic iCre sequence, we explored whether these residues could serve as potential translation start sites, resulting in truncated isoforms that might retain recombinase activity. To address this question, we tested in HEK293T cells whether site-specific recombination was retained in progressively amino-terminal deleted iCre isoforms. Our results reveal residual enzymatic activity of most amino-terminal deleted isoforms of iCre whose ATG start codon is located downstream of the commonly used split site. This insight holds significance for future refinements of the widely used Split-Cre system, providing information to avoid false positive results stemming from unwanted activity.</div></div>","PeriodicalId":52676,"journal":{"name":"Current Research in Biotechnology","volume":"8 ","pages":"Article 100263"},"PeriodicalIF":3.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142526261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work investigates the biodegradation of AMPA by bacteria isolated from three environmental sources, with a focus on determining their potential application in water treatment systems. Two samples were collected from granular activated carbon (GAC) filters of different operational durations at a water treatment facility, and one sample was taken from soil that had historically been treated with glyphosate-based herbicides. Bacterial isolates capable of degrading AMPA were identified from these samples through selective enrichment, and kinetic degradation experiments were then conducted to assess their effectiveness. In environmental samples, after 48 hrs AMPA removal was &gt; 70 % using GAC from an active treatment plant and soil samples removed 19 %. After bacterial isolation a consortium was isolated and from these four isolates were identified, comprising three species, including novel AMPA degraders M−S3 and M−SS (<em>Myroides sp</em>. mNGS23), and P-S92 (<em>Pseudochrobactrum saccharolyticum</em>). Within both minimal media supplemented with AMPA and raw untreated showing substrate concentrations above 10 mg/L whilst the specific degradation rates saw a decrease in substrate concentrations above 100 mg/L. AMPA removal occured in pilot scale sand filters augmented with P-S92 but removal was inconsistent. These findings show the potential of using biodegradation as an effective treatment strategy for AMPA removal from water. The identification of AMPA-degrading bacteria offers a promising solution for enhancing the removal of this persistent pollutant from contaminated waters.
