== Function == | |||
[[http://www.uniprot.org/uniprot/HPAHR_ACIBA HPAHR_ACIBA]] Reductase component of a two-component system that supplies reduced FMN (FMNH2) to the oxygenase component to catalyze the hydroxylation of 4-hydroxyphenylacetic acid, leading to the production of 3,4-dihydroxyphenylacetate (3,4-DHPA). Catalyzes the reduction of free flavins (FMN, FAD and riboflavin) by NADH. Subsequently, the reduced flavins diffuse to the oxygenase component C2.<ref>PMID:11683878</ref> <ref>PMID:16042421</ref> <ref>PMID:17595116</ref> | |||

== Publication Abstract from PubMed == | |||
p-Hydroxyphenylacetate 3-hydroxylase (HPAH) from Acinetobacter baumannii catalyzes the hydroxylation of p-hydroxyphenylacetate (HPA) at the ortho position to yield 3,4-dihydroxyphenylacetate (DHPA). HPAH from A. baumannii is a two-component flavoprotein consisting of a smaller reductase (C(1)) component and a larger oxygenase (C(2)) component. The C(1) component supplies a reduced flavin in its free form to the C(2) counterpart for hydroxylation. In addition, HPA can bind to C(1) and enhance the flavin-reduction rate without becoming hydroxylated. The recombinant C(1) component was purified and crystallized using the microbatch method at 295 K. X-ray diffraction data were collected to 2.3 A resolution using synchrotron radiation on the BL13B1 beamline at NSRRC, Taiwan. The crystal belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 47.78, b = 59.92, c = 211.85 A, and contained two molecules of C(1) per asymmetric unit. | |||
