I think the word you're looking for is:

the most important member of a group or part of a system, that holds together the other members or parts or makes it possible for them to operate as intended

You might also use :

an important person, company, etc. in a particular area of activity:



Something or someone that is indispensable is so good or important that you could not manage without it, him, or her:

His long experience at the United Nations makes him indispensable to the talks.
