== Function == | |||
'''Siderocalin''' (Scn) or '''neutrophil gelatinase-associated lipocalin''' binds ferric siderophores in order to intercept delivery of iron to bacteria which require it thus impeding their virulence<ref>PMID:19053425</ref>. | |||
== Relevance == | |||
Scn-NGAL levels are markedly upregulated by tissue damage. Scn-NGAL is derived from damaged kidneys. The presence of Scn-NGAL in serum or urine anticipates a severe course for the patient including the need for dialysis and the possibility of death<ref>PMID:22728330</ref>. | |||
== Structural highlights == | |||
Scn-NGAL interacts with the <scene name='48/488406/Cv/4'>siderophore carboxymycobactin where the latter is centered in the protein calyx</scene> making <scene name='48/488406/Cv/5'>multiple interactions including cation-π bonds involving several lysines and arginine</scene><ref>PMID:15642259</ref>. Water molecules are shown as red spheres. <scene name='48/488406/Cv/6'>Fe coordination site</scene>. | |||
