Structural characterization of human histidine triad nucleotide-binding protein 2, a member of the histidine triad superfamily.
The histidine triad proteins (HITs) constitute a large and ubiquitous superfamily of nucleotide hydrolases. The human histidine triad nucleotide-binding proteins (hHints) are a distinct class of HITs noted for their acyl-AMP hydrolase and phosphoramidase activity. The first high-resolution crystal structures of hHint2 with and without bound AMP are described. The differences between hHint2 and ...
متن کاملInsight into the Evolution of the Histidine Triad Protein (HTP) Family in Streptococcus
The Histidine Triad Proteins (HTPs), also known as Pht proteins in Streptococcus pneumoniae, constitute a family of surface-exposed proteins that exist in many pathogenic streptococcal species. Although many studies have revealed the importance of HTPs in streptococcal physiology and pathogenicity, little is known about their origin and evolution. In this study, after identifying all htp homolo...
متن کاملFHIT (fragile histidine triad)
Fhit protein is a tumor suppressor with reduced or no expression in many types of cancer. Fhit expression is more frequently lost in cancers of individuals with familial mutations causing deficiency in DNA repair genes such as BRCA1 and BRCA2 and MSH2. In vitro Fhit acts as a hydrolase that cleaves diadenosine triphosphate (Ap3A) to ADP and AMP. The Fhit-Ap3A enzyme-substrate complex appears to...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولKinetic mechanism of human histidine triad nucleotide binding protein 1.
Human histidine triad nucleotide binding protein 1 (hHint1) is a member of a ubiquitous and ancient branch of the histidine triad protein superfamily. hHint1 is a homodimeric protein that catalyzes the hydrolysis of model substrates, phosphoramidate and acyl adenylate, with a high efficiency. Recently, catalytically inactive hHint1 has been identified as the cause of inherited peripheral neurop...
