FunFam 40472: 30S ribosomal protein S1

There are 4 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

    Polyribonucleotide nucleotidyltransferase. [EC: 2.7.7.8]
    RNA(n+1) + phosphate = RNA(n) + a nucleoside diphosphate.
    • ADP, IDP, GDP, UDP and CDP can act as donors.

    4-hydroxy-3-methylbut-2-enyl diphosphate reductase. [EC: 1.17.7.4]
    (1) Isopentenyl diphosphate + 2 oxidized ferredoxin [iron-sulfur] cluster + H(2)O = (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H(+). (2) Dimethylallyl diphosphate + 2 oxidized ferredoxin [iron-sulfur] cluster + H(2)O = (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H(+).
    • Forms a system with a ferredoxin or a flavodoxin and an NAD(P)H-dependent reductase.
    • This is the last enzyme in the non-mevalonate pathway for isoprenoid biosynthesis.
    • This pathway, also known as the 1-deoxy-D-xylulose 5-phosphate (DOXP) or as the 2-C-methyl-D-erythritol-4-phosphate (MEP) pathway, is found in most bacteria and in plant chloroplasts.
    • The enzyme acts in the reverse direction, producing a 5:1 mixture of isopentenyl diphosphate and dimethylallyl diphosphate.
    • Formerly EC 1.17.1.2.

    Dephospho-CoA kinase. [EC: 2.7.1.24]
    ATP + 3'-dephospho-CoA = ADP + CoA.
