Metabolite Identification

Common Name

Lumazine

Description

Lumazine belongs to the class of organic compounds known as pteridines and derivatives. These are polycyclic aromatic compounds containing a pteridine moiety, which consists of a pyrimidine fused to a pyrazine ring to form pyrimido(4,5-b)pyrazine. Lumazine has been detected, but not quantified in, soy beans (Glycine max). This could make lumazine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Lumazine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Lumazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lumazine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzyme Details

1. 6,7-dimethyl-8-ribityllumazine synthase

General function:: Not Available
Specific function:: Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2-butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin.
Gene Name:: RIBH
Uniprot ID:: A6L3K7
Molecular weight:: 18127.525

4. 6,7-dimethyl-8-ribityllumazine synthase 2

General function:: Not Available
Specific function:: Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2-butanone 4-phosphate (PubMed:10482294, PubMed:16165152, PubMed:20195542). This is the penultimate step in the biosynthesis of riboflavin. The isozyme RibH2 but not RibH1 is essential for Brucella intracellular survival and replication inside macrophages or in mice (PubMed:20195542). Displays low catalytic activity in comparison with the isozyme RibH1 (PubMed:16165152). Is a highly immunogenic protein (PubMed:14500496). Activates dendritic cells (DCs) in vitro, increasing the levels of costimulatory molecules and the secretion of proinflammatory cytokines, and recruits DCs, B cells and CD8+ T cells in vivo, both effects in a TLR4-dependent manner (PubMed:16455994). Induces the cross presentation of covalently attached peptides and generates a strong and long-lasting humoral immune response without adjuvants; TLR4 signaling is necessary for the induction of the cytotoxic response but not for antigen cross presentation (PubMed:23029192). Elicits a TLR4-mediated protective response against B16 melanoma in mice, slowing tumor growth and prolonging mice survival (PubMed:25973756).
