Application

Citrate Lyase from Klebsiella pneumoniae has been used in the digestion of low molecular weight human milk fraction (>5 kDa referred to as 5kF).

Biochem/physiol Actions

Citrate lyase is found in several microorganisms and catalyzes the first step of citrate degradation, forming acetate and oxaloacetate. The enzyme contains 3 polypeptide subunits, α-subunit (a transferase), β-subunit (acyl lyase) and γ-subunit (acyl-carrier protein).

Unit Definition

One unit will convert 1.0 μmole of citrate to oxalacetate per min at pH 7.6 at 25 °C.

Physical form

Lyophilized powder containing bovine serum albumin, sucrose, and MgSO4

In this paper, we describe two open reading frames coding for a NAD-dependent malic enzyme (mae) and a putative regulatory protein (clyR) found in the upstream region of citCDEFG of Leuconostoc mesenteroides subsp. cremoris 195. The transcriptional analysis of the

Fatty acid biosynthesis is essential for the survival of Mycobacterium tuberculosis and acetyl-coenzyme A (acetyl-CoA) is an essential precursor in this pathway. We have determined the 3-D crystal structure of M. tuberculosis citrate lyase beta-subunit (CitE), which as annotated should

We demonstrate a facile blue native polyacrylamide gel electrophoresis (BN-PAGE) technique to detect two malate-generating enzymes, namely fumarase (FUM), malate synthase (MS) and four oxaloacetate-forming enzymes, namely pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK), citrate lyase (CL) and aspartate aminotransferase (AST).

In this study we describe the expression pattern of the Leuconostoc paramesenteroides citMCDEFGRP operon in response to the addition of citrate to the growth medium. An 8.8-kb polycistronic transcript, which includes the citMCDEFGRP genes, was identified; its synthesis was dramatically

A turn-on fluorescent indicator for citric acid (citrate) has been developed, displaying high emission enhancement (+1500%) and low interference by other carboxylates. The sensor is based on the non-emissive copper(II) complex of a fluorescent amino amide, which, upon addition of
