【资源简介】
This is
a web-based approach implementing a new java
applet that enables to assign a
chemical structure to the corresponding
NMR spectrum by simply drawing lines between
atoms and automatically characterized
signals.
This NMR predictor
allows to predict the spectrum from the chemical
structure based on
Spinus (Structure-
based Predictions In NUclear magnetic resonance
Spectroscopy), which
is an on-going
project for the development of structure-based
tools for fast prediction of
NMR
spectra
developed
by
Gasteiger
(/services/spinus/). SPINUS

currently
accepts molecular structures via a Java molecular
editor
, and estimates 1H NMR

BioMagResBank (BMRB):
多肽、蛋白质、核酸等的核磁共振数据存储库
【资源简介】
Introduction
BioMagResBank (BMRB) is the publicly-
accessible depository for NMR results from
peptides,
proteins, and nucleic acids
recognized by the International Society of
Magnetic Resonance
and by the IUPAC-
IUBMB-IUPAB Inter-Union Task Group on the
Standardization of Data
Bases of
Protein and Nucleic Acid Structures Determined by
NMR Spectroscopy. In addition,
BMRB
provides reference information and maintains a
collection of NMR pulse sequences
and
computer software for biomolecular NMR. Access to
data in BMRB is free directly from
its
web
site
(URL )
and
ftp
site
()
and
will
remain
so
as
public
funding
permits.
The
concept
of
a
biomolecular
NMR
data
bank
developed
under
a
five-year
research
grant
awarded
to
the
University
of
Wisconsin-Madison
from
the National Library of Medicine,
National Institutes of
Health.
This grant was phased out after that
period, and a Request for Applications was issued
by
the NIH for future support of this
activity. BMRB at t he University of Wisconsin-
Madison
won this competition, has been
supported since 1 September 1996 by the National
Library
of Medicine, NIH under grant 1
P41 LM05799. The current award for five years
expires on
31 August 2004.
Aims
In
collaboration with the Protein Data Bank (PDB,
Brookhaven National Laboratories) and
Nucleic
Acid
Data
Bank
(NDB,
Rutgers
University),
BMRB
aims
to
develop
into
the
collection site for structural NMR data
in proteins and nucleic acids. Steps are being
taken
at BMRB to achieve this
capability, which will include transmission of all
relevant data to the
PDB and NDB
collections. In addition, BMRB has the goal of
archiving NMR-specific data
including
assigned chemical shifts, J-couplings, relaxation
rates, and chemical information
derived
from NMR investigations (for example, hydrogen
exchange rates and pKa values).
In
developing these collections BMRB intends to be
responsive to the needs and priorities
of the scientific community. The
operating policy at BMRB is monitored and shaped
by its
Advisory
Board
which
meets
once
each
year
to
review progress
and
set
priorities.
The
Advisory
Board is composed of representatives from
laboratories that originate and/or use
data within the BMRB p urview.
