General description

Chloramphenicol Acetyl Transferases (CATs) shows conservation and differences in their amino acid sequences. CAT is encode by cat gene and exists as monomer and later assemble into a trimer.

Specificity

Anti-Chloramphenicol Acetyl Transferase (CAT) antibody is specific for bacterial CAT and recombinant CAT expressed in transfected eukaryotic cells (a predominant band of approx. 26 kD).

Immunogen

bacterial chloramphenicol acetyl transferase (CAT).

Application

Anti-Chloramphenicol Acetyl Transferase (CAT) has been used in
  • immunoblotting
  • indirect immunofluorescence
  • immunofluorescence microscopy

Biochem/physiol Actions

Bacterial chloramphenicol acetyl transferase (CAT) is an enzyme that catalyzes the inactivation of the antibiotic, chloramphenicol, by acetylation and subsequently confers bacterial resistance to the antibiotic. CAT, being a stable prokaryotic enzyme, is often used as a reporter gene in transfection assays developed for eukaryotic promoters. Quantification of reporter gene expressions, such as that of CAT, can be correlated to the transcriptional functions of the target sequence. Thus, antibodies directed against CAT can be used for the study of gene sequences that are fused to the CAT reporter gene
Anti-Chloramphenicol Acetyl Transferase (CAT) antibody is specific for bacterial CAT and recombinant CAT expressed in transfected eukaryotic cells (a predominant band of approx. 26 kD). Staining of CAT by the antibody is inhibited by the bacterial CAT antigen in cells transfected with CAT.

Physical form

Naturally occurring chloramphenicol resistance in bacteria is normally due to the presence of the antibiotic inactivating enzyme chloramphenicol acetyltransferase (CAT) which catalyzes the acetyl-S-CoA-dependent acetylation of chloramphenicol at the 3-hydroxyl group. The product 3-acetoxy chloramphenicol does not bind to bacterial

In this work, we describe the identification of synthetic, controllable promoters that function in the bacterial pathogen Francisella novicida, a model facultative intracellular pathogen. Synthetic DNA fragments consisting of the tetracycline operator (tetO) flanked by a random nucleotide sequence were

DRBD13 RNA-binding protein (RBP) regulates the abundance of AU-rich element (ARE)-containing transcripts in trypanosomes. Here we show that DRBD13 regulates RBP6, the developmentally critical protein in trypanosomatids. We also show DRBD13-specific regulation of transcripts encoding cell surface coat proteins including
