  2. Nuclease S1 - Wikipedia

    en.wikipedia.org/wiki/Nuclease_S1

    Nuclease S1 (EC 3.1.30.1) is an endonuclease enzyme that splits single-stranded DNA (ssDNA) and RNA into oligo- or mononucleotides. This enzyme catalyses the following chemical reaction Endonucleolytic cleavage to 5'-phosphomononucleotide and 5'-phosphooligonucleotide end-products

  3. Sphingosine-1-phosphate - Wikipedia

    en.wikipedia.org/wiki/Sphingosine-1-phosphate

    S1P is formed from ceramide, [1] which is composed of a sphingosine and a fatty acid. Ceramidase, an enzyme primarily present in plasma membrane, will convert ceramide to sphingosine. [1]

  4. Upstream and downstream (DNA) - Wikipedia

    en.wikipedia.org/wiki/Upstream_and_downstream_(DNA)

    Due to the anti-parallel nature of DNA, this means the 3' end of the template strand is upstream of the gene and the 5' end is downstream. Some genes on the same DNA molecule may be transcribed in opposite directions. This means the upstream and downstream areas of the molecule may change depending on which gene is used as the reference.

    en.wikipedia.org/wiki/Biochemical_engineering

    Bioreactor. Biochemical engineering, also known as bioprocess engineering, is a field of study with roots stemming from chemical engineering and biological engineering.It mainly deals with the design, construction, and advancement of unit processes that involve biological organisms (such as fermentation) or organic molecules (often enzymes) and has various applications in areas of interest ...

  6. Directionality (molecular biology) - Wikipedia

    en.wikipedia.org/wiki/Directionality_(molecular...

    The relative positions of structures along strands of nucleic acid, including genes and various protein binding sites, are usually noted as being either upstream (towards the 5′-end) or downstream (towards the 3′-end). (See also upstream and downstream.) Directionality is related to, but different from, sense.

  7. Bioprocess - Wikipedia

    en.wikipedia.org/wiki/Bioprocess

    The upstream part of a bioprocess refers to the first step in which microbes/cells are grown, e.g. bacterial or mammalian cell lines (see cell culture), in bioreactors. Upstream processing involves all the steps related to inoculum development, media development, improvement of inoculum by genetic engineering process, optimization of growth ...

    Upstream and downstream (DNA), determining relative positions on DNA; Upstream and downstream (transduction) determining temporal and mechanistic order of cellular and molecular events of signal transduction

  9. Mung bean nuclease - Wikipedia

    en.wikipedia.org/wiki/Mung_bean_nuclease

    Mung bean nuclease (Nuclease MB) is a nuclease derived from sprouts of the mung bean (Vigna radiata) that removes nucleotides in a step-wise manner from single-stranded DNA molecules (ssDNA) and is used in biotechnological applications to remove such ssDNA from a mixture also containing double-stranded DNA (dsDNA).
