Abstract: <p>Flavohemoglobins are enzymes primarily implicated in nitrosative stress due to their high nitric oxide (NO) dioxygenase activity and transcriptional upregulation in response to NO. Giardia intestinalis assemblages A, B, and E possess flavohemoglobins (gFlHb) that may function beyond their NO dioxygenase activity, potentially contributing to oxidative stress regulation, as transcriptional… more
