Conjugated proteins, Biology

CONJUGATED PROTEINS

Besides being made of polypeptides, the conjugated proteins posses additional groups, metals or ions.

Consists of protein and non-protein parts.

Nucleoprotein --             Protein + Nucleic acids(DNA/RNA).

                                     Ribosomes - RNA + Protein

                                     Chromosomes - DNA + Protein

Chromoprotein --           Colourful protein consists of Protein + Pigment, eg. Haemoglobin,Chlorophyll

Phosphoprotein --             Consists of Protein + Phosphate group, eg. Casein protein (milk),

                                     Phosvitin (Egg yolk), Ovovitellin (Egg yolk)

Metaloprotein --             Consists of Protein + Metal

                                     Carbonic anhydrase enzyme (in this Zn is present)

                                     Hexokinase enzyme - Activator is Mg++

                                     Xanthonine oxidase enzyme - Activator is Mo

                                     Tyrosinase enzyme - Activator is Cu.

                                     Aconitase enzyme - Activator is Fe++

Lecithoprotein --               Consists of Lecithin + Protein

                                     Fibrinogen

Lipoprotein ---              Consists of Lipids + Protein, present in plasma membrane

Glycoprotein ---             Consists of Carbohydrate (< 4%) + Protein

                                    Mucin - Present in saliva.

Mucoprotein ---             Consists of Carbohydrate (> 4%) + Protein
