                             WORKSHOP ANNOUNCEMENT

                   STRUCTURAL BIOLOGY OF RESPIRATORY ENZYMES
                CRYSTALLOGRAPHY AND NMR OF MEMBRANE PROTEINS

                              August 16-17, 1993

                         National Institutes of Health
                        Building 31C, Conference Room 6
                              Bethesda, Maryland


The objectives of the meeting will be to determine:

1) the state of the art in the field of membrane protein crystallography,
2) the state of the art in NMR spectroscopy of membrane proteins,
3) the feasibility of achieving atomic resolution structures for the
   respiratory enzymes within the next five to ten years,
4) obstacles and opportunities toward achieving that goal, and
5) models for productive research collaboration on these problems.

The scope of the meeting will include an overview of work on all integral
membrane proteins and the problems common to determining their structures.
The meeting will then focus on the following systems:

1) mitochondrial electron transport proteins and their microbial counterparts,
2) plant and bacterial photoreaction centers and electron transport chains,
3) ATP synthases and other ion-motive ATPases, and
4) membrane transport proteins required for oxidative and photosynthetic
   phosphorylation.

The meeting will feature a series of overview lectures during the morning of
the first day to present the state of the art in five key scientific areas.
The same topics will be revisited in the afternoon by panel discussions
devoted to updates and a critical review of these areas.  The second day will
be devoted to developing specific recommendations to stimulate work in this
area.  A report of the workshop and its recommendations will be presented to
the NIGMS Advisory Council.  Refer to the following Workshop Agenda for
details.

You are invited to attend this workshop and to contribute to the panel
discussions and recommendations development session.  Registration is required
since the number of attendees that can be accommodated is limited.  No
registration fee is involved.  Please return the enclosed Meeting Reservation
Form if you wish to attend.  We have reserved a block of rooms at the Bethesda
Hyatt Regency Hotel near the NIH Campus.  Let us know if you plan to stay at
this hotel and we will be pleased to arrange your reservations.
Unfortunately, we will not be able to provide financial support for your
attendance at this meeting.

If you will not able to attend, but would like to comment on the potential for
stimulating research in this area, please write to me directly.  I will make
your letter available to the workshop participants and include a consensus of
these letters in the report to the NIGMS Advisory Council.Sincerely yours,
