Purification of Leuconostoc mesenteroides citrate lyase and cloning and characterization of the citCDEFG gene cluster
1998
ABSTRACT A citrate lyase (EC 4.1.3.6 ) was purified 25-fold from Leuconostoc mesenteroides and was shown to contain three subunits. The first 42 amino acids of the β subunit were identified, as well as an internal peptide sequence spanning some 20 amino acids into the α subunit. Using degenerated primers from these sequences, we amplified a 1.2-kb DNA fragment by PCR from Leuconostoc mesenteroides subsp. cremoris . This fragment was used as a probe for screening a Leuconostoc genomic bank to identify the structural genes. The 2.7-kb gene cluster encoding citrate lyase of L. mesenteroides is organized in three open reading frames, citD , citE , and citF , encoding, respectively, the three ci…
Purification and characterization of an inducible p-coumaric acid decarboxylase from Lactobacillus plantarum
2006
Abstract Lactobacillus plantarum cells displayed substrate-inducible decarboxylase activities on p-coumaric and ferulic acids of 0.6 and 0.01 μmol min−1 mg−1, respectively. Activity in uninduced cells or corresponding cell extracts was undetectable (
