Allgemeine Beschreibung

Phosphorylase b is a dimer, usually exists in inactive form in the skeletal muscles.[1][2] Equilibrium exists between an active relaxed (R) state and a less active tense (T). Phosphorylase b favors the T state.[3] The enzyme possesses three domains, the N-terminal domain, glycogen-binding domain and the C-terminal domain.[1]

Anwendung

Phosphorylase b from rabbit muscle has been used as a molecular weight marker in 12% polyacrylamide gel for keratinase,[4] and stress-70 protein.[5]
Phosphorylase b from rabbit muscle is to be used as a marker in SDS-PAGE. Phosphorylase b is used during chemical cross-linking studies as a SDS-PAGE molecular weight standard[6][7].

Questions

1–2 of 2 Questions  
  1. Has the amino acid sequence of phosphorylase from rabbit muscle been published?

    1 answer
    1. The sequence has been published. The amino acid composition is:Asp5l, Asn45, Thr35, Ser29, Glu64, Gln31, Pro36, Gly48, Ala63, Cys9, Val62, Met2l, Ile49, Leu79, Tyr36, Phe38, Trp12, Lys48, HiS22, and Arg63. Reference for the sequence and amino acid composition: K. Titani et al., Proc. Nat. Acad. Sci., USA, 74, 4762-4766 (1977) (see attached pdf).Product P1261 is phosphorylase a, which is the tetrameric form. Products P4649 and P6635 are phosphorylase b, the dimeric  form. The sequence information of the subunit would be the same for both forms.
