|Gene:||sucP||Accession Number: G-9706 (MetaCyc)|
Species: Bifidobacterium adolescentis
Subunit composition of
sucrose phosphorylase = [SucP]2
sucrose phosphorylase subunit = SucP
The recombinant enzyme was expressed in Escherichia coli and purified. The native molecular mass was determined by gel permeation chromatography. Sucrose phosphorylases are members of the glycosyl hydrolase family 13 [vandenBroek04]. The crystal structure of this enzyme has been refined at a resolution of 1.77 Å [Sprogoe04].
The molecular mass of the subunit was determined by SDS-PAGE [vandenBroek04].
Molecular Weight of Polypeptide: 56.19 kD (from nucleotide sequence), 58 kD (experimental) [vandenBroek04 ]
Molecular Weight of Multimer: 129 kD (experimental) [vandenBroek04]

In Pathways: sucrose degradation IV (sucrose phosphorylase)
Sucrose phosphorylase reversibly catalyzes the phosphorolysis of sucrose. It also has transglucosylation activity [vandenBroek04].
T(opt): 48 °C [vandenBroek04]
pH(opt): 6.0-6.5 [vandenBroek04]
