Primary structure of p-hydroxybenzoate hydroxylase from Pseudomonas fluorescens
Abstract:
The amino acid sequence of the p-hydroxybenzoate hydroxylase (4-hydroxybenzoate,NADPH:oxygen oxidoreductase (3-hydroxylating), EC 1.14.13.2) monomer from Pseudomonas fluorescens has been determined. The sequence was elucidated by a combination of the results from an X-ray crystallographic study at 0.25 nm resolution (Wierenga, R.K., de Jong, R.J., Kalk, K.H., Hol, W.G.J. and Drenth, J. (1979) J. Mol. Biol. 131, 55-73) and from protein sequence analysis. The polypeptide chain of the monomer contains 394 amino acids and has a molecular weight of 44 299.

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...
