Microbial Iron Acquisition Pathway

Molecular classification: Pathway, Siderophore biosynthesis, Heme uptake system, Transporter, Receptor, Enzyme

Overview

The microbial iron acquisition pathway encompasses the diverse strategies and molecular systems that microorganisms use to obtain iron from their environment or host. Iron is essential for nearly all bacteria and fungi, playing a critical role in DNA replication, transcription, metabolism, and energy generation. Microbes use siderophores, heme uptake systems, and direct uptake from host proteins to acquire iron. Disruption of these pathways can attenuate virulence or growth, making them potential therapeutic targets.

Mechanism of action

Inhibition of siderophore production/uptake, disruption of heme uptake, blocking iron transport
