- * Phosphorylase pyridoxal-phosphate attachment site *
- *****************************************************
-
- Phosphorylases (EC 2.4.1.1) [1] are important allosteric enzymes in
- carbohydrate metabolism. They catalyze the formation of glucose 1-phosphate
- from polyglucose. Enzymes from different sources differ in their regulatory
- mechanisms and their natural substrates. However, all known phosphorylases
- share catalytic and structural properties. They are pyridoxal-phosphate
- dependent enzymes; the pyridoxal-P group is attached to a lysine residue
- around which the sequence is highly conserved and can be used as a signature
- pattern to detect this class of enzymes.
-
- -Consensus pattern: E-A-S-G-x-[GS]-N-M-K
- [K is the pyridoxal-P attachment site]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
- -Last update: October 1993 / Pattern and text revised.
