The MCC Journal Club is for anyone interested in participating in discussion of important papers relating to structure-function relationships in Malate Dehydrogenases.

The Journal Club meets on the second Thursday of each Month and will discuss the primary paper assigned for the topic together with snippets of related papers. Topics to be discussed and links to the appropriate papers can be found on the schedule below together with the zoom link for the session. After each session the powerpoint from the session will be linked to this page.

Each Session a Primary Paper will be presented and discussed together with relevant snippets from secondary papers

All primary papers are freely accessible via PubMed- links given.

See the Topics and papers here- password protected- contact Ellis Bell, jbell@sandiego.edu to obtain the password
